차동 대기압 센서 -SDP31, I2C
(SparkX Differential Pressure Sensor - SDP31 (Qwiic))
개요
- 본 제품은 차동 대기압 센서 -SDP31, I2C입니다.
- SDP31 차동 대기압 센서는 공기의 흐름과 공기의 속도를 측정하는데 적합한 센서입니다.
- 드론이나 비행체에 사용하여 속도를 측정하는데 사용할 수 있습니다.
- +/- 500 Pascals (+/- 0.005 Atm) 대기압의 측정이 가능합니다.

-
As usual, our board includes a power LED, a pair of Qwiic connectors, I2C 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.
OpenLog Artemis provides full support for data logging with the SDP31.
Our Arduino library contains example sketches for the Arduino IDE to get you up and running quickly. There are examples for both single-shot (triggered) and continuous measurements.
