Fermion: URM37 Ultrasonic Distance Sensor Breakout (2～800cm, RS232 / UART) SF_SDR Not sure which accelerometer isURM37 V5. 0 is a powerful ultrasonic sensor module with built in temperature compensation to ensure accurate distance measurement in the scene of temperature changing applications. It has a rich interface and offers various outputs: analog output, switch, serial (TTL and RS232 level optional), PWM, and so on. With analog mode, the sensor outputs voltage which is proportional to distance, it can be connected to Arduino , Raspberry Pi , and LattePanda
