2 efficiently. Remote controlling of the devices gives number of advantages to senior citizens and people with disabilities.so that helps to increase there living style being more autonomous. In addition to remote control and monitoring temperature, humidity,carbon monoxide level in homes is also a major concern. There is a need to monitor temperature, level of gases as they can be very dangerous. Low temperature sensor monitoring warning about freezing inside house. Also there is any leak in the boiler, washer or pipes, it can cause considerable damage.the proposed system shown in figure.2,is cost effective and controlled by user friendly micro-controller embedded systems. The block diagram of the proposed system is as shown in figure 2. In this proposed system, we have designed one master module which consists of ARM based microcontroller, GSM module and RF module.

METHODOLOGY In this proposed system we design Master and Slave system. In slave module we have used AVR microcontroller along with RF module and sensors for monitoring the environment. In high speed data sensing system there are number of sensors connected with the slave module like Gas sensor, Humidity sensor, Temperature sensor. The devices which are to require to be controlled remotely can be connected with the slave module. 2.1 Concept of Master system In master system, we have used ARM7 based LPC21 48 micro-controller. LPC2148 is 32/1 6 bit microcontroller. Its embedded high speed flash memory is about 512 KB. For GSM communication we have used STM300. It is a tri band GSM/GPRS engine. The SIM 300 is integrated with the AT commands and are developed to use TCP/TP protocol easily, which is very useful for data transfer applications. So the AT commands are used by GSM module via its serial interface to control the devices. Radio frequency technology is used for wireless personal area networking. Radio frequency technology offers simplicity and a cost effective approach to building, construction and remodelling with wireless technology. Block diagram of Mastersystem is as follows; 2 Ms.Priyanka. B. Kor, Prof. Mujib. A. Tamboli

A 128-bit wide memory interface with a unique accelerator architecture enable code execution of 32 bit having maximum clock rate. Also the alternative 16-bit Thumb mode will reduces code by more than 30 % with minimal performance penalty of critical code size system. As small size and low power consumption, LPC2148 are ideal in various system. It is used for applications where miniaturization is a key requirement, such as access control and point-of-sale. Serial communications interfaces having ranges from a USB 2.0 Full-speed device, multiple UARTs, SPI, SSP to I2C-bus and on-chip SRAM of 8 kb up to 40 kb. So it will make these devices compatible for communication gateways and protocol converters, soft modems, voice recognition and low end imaging, providing both large buffer size and high processing power. Also for industrial control and medical systems number of 32-bit timers, single or dual 10-bit ADC(s), 10-bit DAC, PWM channels and 45 fast GPIO lines with up to nine edge or level sensitive external interrupt pins make these microcontrollers suitable for system SIM300 GSM module GSM/GPRS RS232 Modem is develop with SIMCOM gives SIM900 Quad-band GSM/GPRS engine. It is works on frequencies 850 MHz, 900 MHz, 1800 MHz and 1900 MHz. It is very compressed in size and simple for plug in GSM Modem. The Modem is designed with the help of RS232 Level converter circuitry. So it will allows you to directly interface PC Serial port. We can be configure the baud rate from through AT command. Firstly Modem is in Auto baud mode. This GSM/GPRS RS232 Modem is having internal TCP/IP stack to initiate connection with internet via GPRS. It is compatible to send SMS as well as DATA transfer application in M2M interface. The modem required only 3 wires (TX, Rx, GND) except Power supply to interface withmicrocontroller/host PC. The built in Low Dropout characteristic of Linear voltage regulator allows you to connect wide range of unregulated power supply (4.2V -13V). So it is 5 V is in between!!. In this proposed system, using simple AT command you will be able to send & Read SMS, connect to internet via GPRS RF Module RF module (radio frequency module) is a small electronic circuit used to transmit and receive radio signals on one of a number of carrier frequencies. RF modules are widely used in Electronics,Telecommunication and designing radio circuitry. RF modules are most often applied in medium and low volume products depending 3 Ms.Priyanka. B.

4 on consumer applications such as wireless alarm systems, industrial remote controls, smart sensor applications, and wireless home automation systems. Commercially available RF module having frequencies are MHz, 315 MHz, 868 MHz and 915MHz. These frequencies are used because of national and international regulations governing the use radio as communication medium. 2.2 Concept of Slave system In slave module we have used AVR microcontroller along with RF module and sensors for monitoring the environment. In high speed data sensing system we are connect various sensors with the slave module are Gas sensor, Humidity sensor, Temperature sensor.the devices which are to needed to be controlled remotely can be connected with the slave module. In slave system components are used they are as follows: AVR Microcontroller 8 bit RF Module Gas Sensor Temperature Sensor Humidity Sensor Figure.4 Block diagram of Slave System AVR Microcontroller: The Atmel AVR ATmega8 be the low-power CMOS 8-bit microcontroller based on the AVR RISC architecture. Due to execution of powerful instructions in a single clock cycle, the ATmega8 procure throughputs approaching 1MIPS per MHz, allowing the system designed to enhance power consumption versus speed of system processing RF Module The RF Module solves problems in the general field of electromagnetic waves, such as RF and microwave applications, optics and photo static. The underlying equations for electromagnetism are automatically available in all of the physics interfaces a feature unique to COMSOL Multiphasic. This also makes unusual modeling easily accessible. The module is useful for development of component design in virtually all areas where you find electromagnetic waves, such as: Antennas Waveguides and cavity resonators in microwave engineering Optical fibers Photonic waveguides Photonic crystals Active devices in photonics 4 Ms.Priyanka.

5 2.2.3Gas Sensor: The main function of proposed system is to detect the leakage of LPG gas by using gas sensor. LPG gas consists of propane, methane and also Isobutene. Our requirement is to have a gas sensor which gives sensitiveness only for the LPG gas. Also it is less sensitive to other gases like cooking fumes and cigarettes. So that in this system, MQ6 gas sensor is used this has SnO2 sensitive material and lower conductivity in air. This gas sensor is having higher sensitiveness to Propane, Butane and LPG, and also give response to Natural gas. This sensor is having simple drive circuit. Also it is portable gas detector which is having long lifespan and cost effective. It requires the 0-5 volt power supply which is very low as well as safe for gaseous environment. Figure 5.Gas Sensor MQ Temperature Sensor The LM35 series are temperature sensors having precision integrated-circuit, whose output voltage is linearly proportional to the Celsius temperature. Thus the LM35 has an advantageous over liner temperature sensors calibrated in Kelvin, because the user is not needed to subtract a large constant voltage from its output to obtain convenient Centigrade scaling. The LM35 does not needful any external calibration or trimming to provide typical accuracies of ±¼ C at room temperature and ±¾ Cover a full -55 to +150 Ctemperature range.

They are also useful in all applications where humidity compensation is necessary.therefore HS 1101 Humidity sensor is used. Figure 7. HS 1101 Humidity sensor Features- Compatible with automatized assembly processes, including wave soldering, reflow and water immersion High reliability and long term stability Patented solid polymer structure Suitable for linear voltage or frequency output circuitry Fast response time Individual marking for compliance to stringent traceability requirements Full interchange ability with no calibration required in standard conditions Instantaneous desaturation after long periods in saturation phase CONCLUSION In this proposed system we get brief information about high speed data sensing system.
