Copyright 2016 Page 4

5 2.1 Supported Profiles The following profiles are included in the X2M200 module: Respiration Profile Sleep Profile Default factory setting is the Sleep Profile. 3 Sensor operation 3.1 Power-up Configuration Profiles and User Settings can be loaded as described in the Protocol Document. See chapter "The XeThru Serial Protocol" for more details. User Settings vary between different profiles and each profile has its own default setting. See the Profile description chapters for details. If a User Setting is not specified, the default value will be used Settings At power-up, the sensor will start with its stored settings. 3.2 IO-pins Various profiles may have different uses of IO-pins. Do not connect IO-pins that are not in use. The sensor module will pull up these IO-pins internally. Future FW upgrades of the sensor and any existing or future pin compatible products may use these IO-pins for other functionality. 4 XeThru Respiration Profile 4.1 Overview The XeThru Respiration Profile works by measuring the minute periodic movements of the human body while at rest. This profile is optimized to measure the respiration of a person who is awake with the sensor placed at the height of the chest or abdomen pointing towards the chest or abdomen. The body part generating the best signal will vary from person to person. Some breathe shallo wly, drawing air into the chest area and thus the largest movement will come from the chest. While others breathe deeper, expanding the abdomen rather than the chest. In this case, the abdomen will be the largest movement. Copyright 2016 Page 5

6 The sensor measures the change in distance of an object with respect to the sensor, which allows different sensor placements than the one suggested. 4.2 User Settings Detection Zone The upper limit of the detection zone sets the maximum distance for respiration detection, while the lower limit sets the minimum distance. Detection zone parameter limits Minimum lower range 0.50m Maximum upper range 2.50m Minimum size of detection zone 0.20m Maximum size of detection zone 0.70m The detection zone can be configured with 0.01m resolution Sensitivity Sensitivity settings Minimum sensitivity Maximum sensitivity Sensitivity step size A higher sensitivity setting gives a better sensing of small targets, while a lower sensitivity setting makes the sensor more robust against false detections LED The module has 1 multi color RGB LED. The module LED can be configured to operate in various ways. Full Initializing: Green (0.15sec) -> Orange (0.15sec) -> Red (0.2sec) -> Orange (0.15sec) -> Green (0.15 sec) -> OFF (0.2sec) Breathing: Green on/off flashing 50% duty cycle. Period = RPM (no breathing pattern, RPM =15 means LED flashes 15 times/minute) Movement: Green (0.5sec) -> Orange (0.5sec) No movement: Red (0.3sec) -> off (4.7sec) Simple Copyright 2016 Page 6

7 Initializing: Green (0.15sec) -> Orange (0.15sec) -> Red (0.2sec) -> Orange (0.15sec) -> Green (0.15 sec) -> OFF (0.2sec) Breathing: Green ON Movement: Orange ON No movement: Red (0.3sec)-OFF (4.7sec) Off Initializing: Green ON All other states: OFF Inhalation LED is off except when the sensor has good track of inhale and exhale. Inhale: Blue Exhale: Yellow Default User Settings Default User Settings are applicable when the Sleep Profile is selected, and no User Setting is specified. User Setting Detection zone Default value meter Sensitivity 5 LED Full 4.3 Sensor operation in Respiration Profile Detect presence and breathing The X2M200 sensor detects presence within its detection zone by detecting movement and processing the data. Once the module detects movement, it will attempt to identify a breathing movement. If more than one person is present in the detection zone, the X2M200 sensor will normally measure the one who is closest to the sensor, emitting the strongest signal. However in some cases, the body position and size may give stronger signals at longer distances. There are six states in the Respiration Profile: No Movement No presence detected Movement: Presence, but no identifiable breathing movement Movement Tracking: Presence and possible breathing movement detected Breathing: Valid breathing movement detected Initializing: The sensor initializes after the Respiration Profile is chosen Unknown: The sensor is in an unknown state and requires that the Profile and User Settings are loaded Copyright 2016 Page 7

The length and position of Radar Frames is controlled by the Detection Zone User Setting. The Radar Frame starts 0.1 meter before the start of the Detection Zone and is always 1 meter for the Respiration Profile. Examples of relationship between Detection Zone and Radar Frame Selected Detection Zone Resulting Radar Frame meter meter meter meter meter meter Baseband data is available as an option on the communication port. Baseband data outputs either amplitude and phase information of reflections, or the same data represented with I and Q values. Copyright 2016 Page 9

10 Example of baseband data output The example above shows the amplitude of reflections plotted for a 2 meter Radar Frame. This particular measurement shows two refelections; the first reflection is about 0.1 meter into the Radar Frame, and the second reflection is about 1.2 meter into the Radar Frame. Refer to application notes on for more detalied descriptions on how to use baseband data output. 5 XeThru Sleep Profile 5.1 Overview The XeThru Sleep Profile works by measuring the minute periodic movements of the human body while sleeping. This profile is optimized to give the best possible readings of an adult sleeping in a bed with the sensor placed at a nightstand at the height of the head or upper torso with a minimum 15 cm elevation above the sleeping surface and directed at the target person's chest or abdomen. The body part generating the best signal will vary from person to person. Some breathe shallowly, drawing air into the chest area and thus the largest movement will come from the chest. While others breathe deeper, expanding the abdomen rather than the chest. In this case, the abdomen will be the largest movement. The sensor measures the change in distance of an object with respect to the sensor, which allows different sensor placements than the one suggested. 5.2 User Settings Set Detection Zone The upper limit of the detection zone sets the maximum distance for respiration detection, while the lower limit sets the minimum distance. Detection zone parameter limits Minimum lower range 0.40m Maximum upper range 2.50m Minimum length of detection zone 0.20m Maximum length of detection zone 1.60m Copyright 2016 Page 10

11 The detection zone can be configured with 0.01m resolution Sensitivity Sensitivity settings Minimum sensitivity Maximum sensitivity Sensitivity step size A higher sensitivity setting gives a better sensing of small targets, while a lower sensitivity setting makes the sensor more robust against false detections Configure sensor indicator LED The module has 1 multi color RGB LED. The module LED can be configured between "Full" state indication, a "Simple" indication or "Off", which is convenient for sleep monitoring use.

22 7.6.1 X2M200 Block diagram Module clock and power system Clocks: The systems clocks are all derived from a 12MHz crystal oscillator connected to the main microcontroller. The communication between the microcontroller and the X2 radar uses SPI protocol. The SPI communication clock is set up to run at 30MHz. The PRF (Pulse Repetition Frequency) is the actual radar frame rate (number of radar pulses per second). This frequency can be changed by the microcontroller but cannot exceed 30MHz to comply with FCC regulations. For further description of the radar, please refer to the X2 datasheet, which can be found here: /x2-uwb-radar-chip.html. Power: The module is powered externally from either the USB port or an external power supply. If both power sources are connected, the USB takes precedence over the external power. Antennas: The antennas are embedded onto the PCB and cannot be changed by users. Please refer to the Antennas chapter for details on the antennas Radar functional description The module uses the Novelda X2 single chip radar transceiver.

It should be placed out of reach of humans and protected from enviromental surroundings such as moisture. When placing the module, please pay attention to the following: Point the sensor in the direction of the object or zone to monitor. Refer to the antenna plots for sensitivity plots and opening angles Be aware of indirect reflections. An object that seems to be 1 meter away may also give reflections via the floor, the ceiling or walls Nearby metallic objects should be avoided, especially in the signal path to the sensor's observation area Copyright 2016 Page 23

24 The sensor can be placed on static (non-moving) surfaces such as: On a desk On a wall Behind a wall (*) In the ceiling Behind the ceiling (*) Please note that the sensor is sensitive to vibrations. If vibrations occur, the sensor will see this as noise in the signal and will result in a reduced signal-to-noise ratio. Casing materials: If a sensor casing is required, the material should be of a kind that does not attenuate the high frequency signals in the sensor s main direction. Recommended materials are ABS and other types of non-conductive plastics (*) (*): Different materials will attenuate the signal. A good reference document can be found here: (page 61 onwards) 8.2 Connecting the X2M200 to a host system The X2M200 can be connected to a host system in 3 ways: Via USB Via the interface connector using the UART interface Via the interface connector using the GPIO interface Not all Profiles support the GPIO interface.
