{"product_id":"sparkfun-sparkx-differential-pressure-sensor-sdp31-qwiic","title":"SparkFun SparkX Differential Pressure Sensor - SDP31 (Qwiic)","description":"\u003cp\u003eThe SDP31 differential pressure sensor is ideally suited to air flow rate and air speed measurement. Need an air speed indicator for your drone \/ model aircraft or want to measure flow rate \/ filter clogging in your robot vacuum cleaner? This is the sensor for you!\u003c\/p\u003e \u003cp\u003eThe SDP3x sensor family is Sensirion�s series of small differential pressure sensors designed for high-volume applications where size is a key requirement. It builds on the next generation CMOSens® sensor chip that is at the heart of Sensirion�s new differential pressure and flow sensing platform.\u003c\/p\u003e \u003cp\u003eAble to measure differential pressures in the range +\/- 500 Pascals (+\/- 0.005 Atm), the SDP31 is ideally suited to flow rate and air speed applications. The two mounting holes on our board are aligned with the center of the SDP31 package; the high and low pressure sensing tubes are offset by 0.65mm and separated by 4.3mm. Please consult the datasheet or STEP file for more details.\u003c\/p\u003e \u003cp\u003eThe digital SDP31 sensor features fast measurement speed, excellent accuracy and long-term stability and has no zero-point drift. Furthermore, it is reflow solderable and provides extended functionality, such as smart averaging, multiple temperature compensation modes, configurable I\u003csup\u003e2\u003c\/sup\u003eC address and interrupts. The I\u003csup\u003e2\u003c\/sup\u003eC address can be configured using the split-pad jumpers on the back of the board. The interrupt pin is available on a breakout pad.\u003c\/p\u003e \u003cp\u003eAs usual, our board includes a power LED, a pair of Qwiic connectors, I\u003csup\u003e2\u003c\/sup\u003eC breakout pads and pull-up resistors. You can disable the LED and pull-ups if you need to by cutting the I2C jumpers on the back of the board.\u003c\/p\u003e \u003cp\u003e\u003ca href=\"https:\/\/www.sparkfun.com\/products\/16832\"\u003eOpenLog Artemis\u003c\/a\u003e provides full support for data logging with the SDP31.\u003c\/p\u003e \u003cp\u003eOur \u003ca href=\"https:\/\/github.com\/sparkfun\/SparkFun_SDP3x_Arduino_Library\"\u003eArduino library\u003c\/a\u003e contains example sketches for the Arduino IDE to get you up and running quickly.

All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector.
