12 Datasheet SHTx (SHT0, SHT, SHT5) Humidity and Temperature Sensor Fully calibrated Digital output Low power consumption Excellent long term stability SMD type package reflow solderable Product Summary SHTx (including SHT0, SHT and SHT5) is Sensirion s family of surface mountable relative humidity and temperature sensors. The sensors integrate sensor elements plus signal processing on a tiny foot print and provide a fully calibrated digital output. A unique capacitive sensor element is used for measuring relative humidity while temperature is measured by a band-gap sensor. The applied CMOSens technology guarantees excellent reliability and long term stability. Both sensors are seamlessly coupled to a 4bit analog to digital converter and a serial interface circuit. This results in superior signal quality, a fast response time and insensitivity to external disturbances (EMC). Each SHTx is individually calibrated in a precision humidity chamber. The calibration coefficients are programmed into an OTP memory on the chip. These coefficients are used to internally calibrate the signals from the sensors. The 2-wire serial interface and internal voltage regulation allows for easy and fast system integration. The tiny size and low power consumption makes SHTx the ultimate choice for even the most demanding applications. SHTx is supplied in a surface-mountable LCC (Leadless Chip Carrier) which is approved for standard reflow soldering processes. The same sensor is also available with pins (SHT7x) or on flex print (SHTA). Dimensions 7.47 ± ± ±0..27 ± ±0.05 NC ±0.2 A5Z ±0..5 ±0. NC NC NC NC NC sensor opening 2.5 ± ± ± MAX Sensor Chip SHTx V4 for which this datasheet applies features a version 4 Silicon sensor chip. Besides a humidity and a temperature sensor the chip contains an amplifier, A/D converter, OTP memory and a digital interface. V4 sensors can be identified by the alpha-numeric traceability code on the sensor cap see example A5Z code on Figure. Material Contents While the sensor is made of a CMOS chip the sensor housing consists of an LCP cap with epoxy glob top on an FR4 substrate. The device is fully RoHS and WEEE compliant, thus it is free of Pb, Cd, Hg, Cr(6+), PBB and PBDE. 3.3 ± ± MAX 0.8 ±0. Figure : Drawing of SHTx sensor packaging, dimensions in mm (mm = 0.039inch). Sensor label gives for SHT as an example. Contacts are assigned as follows: :GND, 2:DATA, 3:SCK, 4:VDD. Evaluation Kits For sensor trial measurements, for qualification of the sensor or even experimental application of the sensor there is an evaluation kit EK-H2 available including sensor, hard and software to interface with a computer. For more sophisticated and demanding measurements a multi port evaluation kit EK-H3 is available which allows for parallel application of up to 20 sensors. Version 4.0 July 2008

14 Users Guide SHTx Application Information. Operating Conditions Sensor works stable within recommended normal range see Figure 4. Long term exposures to conditions outside normal range may temporarily offset the RH signal (+3 %RH after 60h). After return to normal range it will slowly return towards calibration state by itself. See Section.4. Reconditioning Procedure to accelerate eliminating the offset. Prolonged exposure to extreme conditions may accelerate ageing. Relative Humidity (%) Max. Range Normal Range Temperature ( C) Figure 4: Operating Conditions.2 Soldering instructions For soldering SHTx standard reflow soldering ovens may be used. The sensor is qualified to withstand soldering profile according to IPC/JEDEC J-STD-020C with peak temperatures at 260 C during up to 40sec including Pbfree assembly in IR/Convection reflow ovens. Temperature TP TL TS (max) preheating Figure 5: Soldering profile according to JEDEC standard. TP <= 260 C and tp < 40sec for Pb-free assembly. TL < 220 C and tl < 50sec. Ramp-up/down speeds shall be < 5 C/sec. For soldering in Vapor Phase Reflow (VPR) ovens the peak conditions are limited to T P < 233 C during t P < 60sec and ramp-up/down speeds shall be limited to 0 C/sec. For manual soldering contact time must be limited to 5 seconds at up to 350 C C = 45 F, 260 C = 500 F, 350 C = 662 F t L t P critical zone Time IMPORTANT: After soldering the devices should be stored at >75%RH for at least 2h to allow the polymer to rehydrate. Otherwise the sensor may read an offset that slowly disappears if exposed to ambient conditions. In no case, neither after manual nor reflow soldering, a board wash shall be applied. Therefore it is strongly recommended to use no-clean solder paste. In case of application with exposure of the sensor to corrosive gases the soldering pads shall be sealed to prevent loose contacts or short cuts. For the design of the SHTx footprint it is recommended to use dimensions according to Figure 7. Sensor pads are coated with 35µm Cu, 5µm Ni and 0.µm Au Ø0.60 Figure 6: Rear side electrodes of sensor, view from top side No copper in this field Figure 7: Recommended footprint for SHTx. Values in mm..3 Storage Conditions and Handling Instructions It is of great importance to understand that a humidity sensor is not a normal electronic component and needs to be handled with care. Chemical vapors at high concentration in combination with long exposure times may offset the sensor reading. For these reasons it is recommended to store the sensors in original packaging including the sealed ESD bag at following conditions: Temperature shall be in the range of 0 C 50 C (0 25 C for limited time) and humidity at 20 60%RH (sensors that are not stored in ESD bags) Version 4.0 July 2008

15 Datasheet SHTx For sensors that have been removed from the original packaging we recommend to stored them in ESD bags made of PE-HD 8. In manufacturing and transport the sensors shall be prevented of high concentration of chemical solvents and long exposure times. Out-gassing of glues, adhesive tapes and stickers or out-gassing packaging material such as bubble foils, foams, etc. shall be avoided. Manufacturing area shall be well ventilated. For more detailed information please consult the document Handling Instructions or contact Sensirion..4 Reconditioning Procedure As stated above extreme conditions or exposure to solvent vapors may offset the sensor. The following reconditioning procedure may bring the sensor back to calibration state: Baking: C at < 5%RH for 0h Re-Hydration: C at ~ 75%RH for 2h 9..5 Temperature Effects Relative humidity reading strongly depends on temperature. Therefore, it is essential to keep humidity sensors at the same temperature as the air of which the relative humidity is to be measured. In case of testing or qualification the reference sensor and test sensor must show equal temperature to allow for comparing humidity readings. If the SHTx shares a PCB with electronic components that produce heat it should be mounted in a way that prevents heat transfer or keeps it as low as possible. Measures to reduce heat transfer can be ventilation, reduction of copper layers between the SHTx and the rest of the PCB or milling a slit into the PCB around the sensor (see Figure 8). A5Z Figure 8: Top view of example of mounted SHTx with slits milled into PCB to minimize heat transfer. Furthermore, there are self-heating effects in case the measurement frequency is too high. Please refer to Section 3.3 for detailed information. 8 For example, please check %RH can conveniently be generated with saturated NaCl solution C correspond to F, C correspond to F.6 Light The SHTx is not light sensitive. Prolonged direct exposure to sunshine or strong UV radiation may age the housing..7 Membranes SHTx does not contain a membrane at the sensor opening. However, a membrane may be added to prevent dirt and droplets from entering the housing and to protect the sensor. It will also reduce peak concentrations of chemical vapors. For optimal response times the air volume behind the membrane must be kept minimal. Sensirion recommends and supplies the SF filter cap for optimal IP54 protection (for higher protection i.e. IP67 - SF must be sealed to the PCB with epoxy). Please compare Figure 9. membrane o-ring SHTx PCB Melted plastic pin housing Figure 9: Side view of SF filter cap mounted between PCB and housing wall. Volume below membrane is kept minimal..8 Materials Used for Sealing / Mounting Many materials absorb humidity and will act as a buffer increasing response times and hysteresis. Materials in the vicinity of the sensor must therefore be carefully chosen. Recommended materials are: Any metals, LCP, POM (Delrin), PTFE (Teflon), PE, PEEK, PP, PB, PPS, PSU, PVDF, PVF. For sealing and gluing (use sparingly): High filled epoxy for electronic packaging (e.g. glob top, underfill), and Silicone. Out-gassing of these materials may also contaminate the SHTx (see Section.3). Therefore try to add the sensor as a last manufacturing step to the assembly, store the assembly well ventilated after manufacturing or bake at >50 C for 24h to outgas contaminants before packing..9 Wiring Considerations and Signal Integrity Carrying the SCK and DATA signal parallel and in close proximity (e.g. in wires) for more than 0cm may result in cross talk and loss of communication. This may be resolved by routing VDD and/or GND between the two data signals and/or using shielded cables. Furthermore, slowing down SCK frequency will possibly improve signal integrity. Power supply pins (VDD, GND) must be decoupled with a 00nF capacitor if wires are used. Version 4.0 July /

16 Datasheet SHTx Capacitor should be placed as close to the sensor as possible. Please see the Application Note ESD, Latchup and EMC for more information..0 ESD (Electrostatic Discharge) ESD immunity is qualified according to MIL STD 883E, method 305 (Human Body Model at ±2 kv). Latch-up immunity is provided at a force current of ±00mA with T amb = 80 C according to JEDEC78A. See Application Note ESD, Latchup and EMC for more information. 2 Interface Specifications Pin Name GND Ground Comment 2 DATA Serial Data, bidirectional 3 SCK Serial Clock, input only 4 VDD Source Voltage NC NC Must be left unconnected Table : SHTx pin assignment, NC remain floating. 2. Power Pins (VDD, GND) The supply voltage of SHTx must be in the range of V, recommended supply voltage is 3.3V. Power supply pins Supply Voltage (VDD) and Ground (GND) must be decoupled with a 00 nf capacitor see Figure 0. The serial interface of the SHTx is optimized for sensor readout and effective power consumption. The sensor cannot be addressed by I 2 C protocol, however, the sensor can be connected to an I 2 C bus without interference with other devices connected to the bus. The controller must switch between the protocols. Micro- Controller (Master) VDD RP 0kΩ V GND DATA SCK VDD 00nF Figure 0: Typical application circuit, including pull up resistor RP and decoupling of VDD and GND by a capacitor. 2.2 Serial clock input (SCK) SCK is used to synchronize the communication between microcontroller and SHTx. Since the interface consists of fully static logic there is no minimum SCK frequency. NC GND A5Z SHTx A5Z (Slave) NC NC NC NC NC 2.3 Serial data (DATA) The DATA tri-state pin is used to transfer data in and out of the sensor. For sending a command to the sensor, DATA is valid on the rising edge of the serial clock (SCK) and must remain stable while SCK is high. After the falling edge of SCK DATA may be changed. For safe communication DATA valid shall be extended T SU and T HO before the rising and after the falling edge of SCK, respectively see Figure. For reading data from the sensor, DATA is valid T V after SCK has gone low and remains valid until the next falling edge of SCK. To avoid signal contention the microcontroller must only drive DATA low. An external pull-up resistor (e.g. 0kΩ) is required to pull the signal high it should be noted that pull-up resistors may be included in I/O circuits of microcontrollers. See Table 2 for detailed I/O characteristic of the sensor. 2.4 Electrical Characteristics The electrical characteristics such as power consumption, low and high level, input and output voltages depend on the supply voltage. Table 2 gives electrical characteristics of SHTx with the assumption of 5V supply voltage if not stated otherwise. For proper communication with the sensor it is essential to make sure that signal design is strictly within the limits given in Table 3 and Figure.

Start up Sensor As a first step the sensor is powered up to chosen supply voltage VDD. The slew rate during power up shall not fall below V/ms. After power-up the sensor needs ms to get to Sleep State. No commands must be sent before that time. 3.2 Sending a Command To initiate a transmission, a Transmission Start sequence has to be issued. It consists of a lowering of the DATA line while SCK is high, followed by a low pulse on SCK and raising DATA again while SCK is still high see Figure 2. THO DATA valid read TV TRO TFO 90% 0% DATA Figure 2: "Transmission Start" sequence The subsequent command consists of three address bits (only 000 is supported) and five command bits. The SHTx indicates the proper reception of a command by pulling the DATA pin low (ACK bit) after the falling edge of the 8th SCK clock. The DATA line is released (and goes high) after the falling edge of the 9th SCK clock. Command Reserved Code 0000x Measure Temperature 000 Measure Relative Humidity 000 Read Status Register 00 Write Status Register 000 Reserved Soft reset, resets the interface, clears the status register to default values. Wait minimum ms before next command Table 4: SHTx list of commands 3.3 Measurement of RH and T 00x-0x 0 90% 0% After issuing a measurement command ( for relative humidity, for temperature) the controller has to wait for the measurement to complete. This takes a maximum of 20/80/320 ms for a 8/2/4bit measurement. The time varies with the speed of the internal oscillator and can be lower by up to 30%. To signal the completion of a measurement, the SHTx pulls data line low and enters Idle Mode. The controller must wait for this Data Ready signal before restarting SCK to readout the data. Measurement data is stored until readout, therefore the controller can continue with other tasks and readout at its convenience. Two bytes of measurement data and one byte of CRC checksum (optional) will then be transmitted. The micro controller must acknowledge each byte by pulling the DATA line low. All values are MSB first, right justified (e.g. the 5 th SCK is MSB for a 2bit value, for a 8bit result the first byte is not used). Communication terminates after the acknowledge bit of the CRC data. If CRC-8 checksum is not used the controller may terminate the communication after the measurement data LSB by keeping ACK high. The device automatically returns to Sleep Mode after measurement and communication are completed. Version 4.0 July /

18 Datasheet SHTx Important: To keep self heating below 0. C, SHTx should not be active for more than 0% of the time e.g. maximum one measurement per second at 2bit accuracy shall be made. 3.4 Connection reset sequence If communication with the device is lost the following signal sequence will reset the serial interface: While leaving DATA high, toggle SCK nine or more times see Figure 3. This must be followed by a Transmission Start sequence preceding the next command. This sequence resets the interface only. The status register preserves its content. SCK DATA Figure 3: Connection Reset Sequence Transmission Start 90% 0% 90% 0% 3.5 CRC-8 Checksum calculation The whole digital transmission is secured by an 8bit checksum. It ensures that any wrong data can be detected and eliminated. As described above this is an additional feature of which may be used or abandoned. Status Register Some of the advanced functions of the SHTx such as selecting measurement resolution, end of battery notice or using the heater may be activated by sending a command to the status register. The following section gives a brief overview of these features. A more detailed description is available in the Application Note Status Register.

Measurement resolution: The default measurement resolution of 4bit (temperature) and 2bit (humidity) can be reduced to 2 and 8bit. This is especially useful in high speed or extreme low power applications. End of Battery function detects and notifies VDD voltages below 2.47 V. Accuracy is ±0.05 V. Heater: An on chip heating element can be addressed by writing a command into status register. The heater may increase the temperature of the sensor by 5 0 C 2 beyond ambient temperature. The heater draws roughly 5V supply voltage. For example the heater can be helpful for functionality analysis: Humidity and temperature readings before and after applying the heater are compared. Temperature shall increase while relative humidity decreases at the same time. Dew point shall remain the same. Please note: The temperature reading will display the temperature of the heated sensor element and not ambient temperature. Furthermore, the sensor is not qualified for continuous application of the heater. 4 Conversion of Signal Output 4. Relative Humidity For compensating non-linearity of the humidity sensor see Figure 8 and for obtaining the full accuracy of the sensor it is recommended to convert the humidity readout (SO RH) with the following formula with coefficients given in Table 6: RH linear 2 RH 3 2 RH = c + c SO + c SO (%RH) 2 Corresponds to 9 8 F SORH c c2 c3 2 bit E-6 8 bit E-4 Table 6: Optimized V4 humidity conversion coefficients The values given in Table 6 are newly introduced and provide optimized accuracy for V4 sensors along the full measurement range. The parameter set c x*, which has been proposed in earlier datasheets, which was optimized for V3 sensors, still applies to V4 sensors and is given in Table 7 for reference. SORH c* c2* c3* 2 bit E-6 8 bit E-4 Table 7: V3 humidity conversion coefficients, which also apply to V4. For simplified, less computation intense conversion formulas see Application Note RH and Temperature Non- Linearity Compensation. Values higher than 99% RH indicate fully saturated air and must be processed and displayed as 00%RH 3. Please note that the humidity sensor has no significant voltage dependency. Relative Humidity 00% 80% 60% 40% 20% 0% SO RH sensor readout (2bit) Figure 8: Conversion from SORH to relative humidity 4.2 Temperature compensation of Humidity Signal For temperatures significantly different from 25 C (~77 F) the humidity signal requires a temperature compensation. The temperature correction corresponds roughly to 0.2%RH/ 50%RH. Coefficients for the temperature compensation are given in Table 8. true ( T C 25) ( t + t 2 SORH ) RHlinear RH + = SORH t t2 2 bit bit Table 8: Temperature compensation coefficients 4 3 If wetted excessively (strong condensation of water on sensor surface), sensor output signal can drop below 00%RH (even below 0%RH in some cases), but the sensor will recover completely when water droplets evaporate. The sensor is not damaged by water immersion or condensation. 4 Coefficients apply both to V3 as well as to V4 sensors. Version 4.0 July /

20 Datasheet SHTx 4.3 Temperature The band-gap PTAT (Proportional To Absolute Temperature) temperature sensor is very linear by design. Use the following formula to convert digital readout (SO T) to temperature value, with coefficients given in Table 9: T = d + d2 SO T VDD d ( C) d ( F) SOT d2 ( C) d2 ( F) 5V bit V bit V V V Table 9: Temperature conversion coefficients Dew Point SHTx is not measuring dew point directly, however dew point can be derived from humidity and temperature readings. Since humidity and temperature are both measured on the same monolithic chip, the SHTx allows superb dew point measurements. For dew point (T d) calculations there are various formulas to be applied, most of them quite complicated. For the temperature range of C the following approximation provides good accuracy with parameters given in Table 0: T d ( RH,T) RH m T ln + 00% Tn + T = Tn RH m T m ln 00% T + T Temperature Range Tn ( C) m Above water, 0 50 C Above ice, C Table 0: Parameters for dew point (Td) calculation. Please note that ln( ) denotes the natural logarithm. For RH and T the linearized and compensated values for relative humidity and temperature shall be applied. For more information on dew point calculation see Application Note Dew point calculation. n 5 Environmental Stability If sensors are qualified for assemblies or devices, please make sure that they experience same conditions as the reference sensor. It should be taken into account that response times in assemblies may be longer, hence enough dwell time for the measurement shall be granted. For detailed information please consult Application Note Qualification Guide. The SHTx sensor series were tested according to AEC- Q00 Rev. F qualification test method. Sensor specifications are tested to prevail under the AEC-Q00 temperature grade 2 test conditions listed in Table 6. Sensor performance under other test conditions cannot be guaranteed and is not part of the sensor specifications.
