Gravity: URM09 Ultrasonic Ranging Sensor

1. Example Code for Arduino-Ultrasonic Distance Measurement

This example is the ultrasonic distance measurement of the module. The mainboard outputs a high-level about tens of microseconds to trigger the sensor to start ranging. Then, the sensor will output a high-level pulse proportional to the ultrasonic flight time. The distance can be easily obtained after a simple calculation by detecting high-level time.

2. Example Code for micro:bit-Ultrasonic Distance Measurement

Use micro:bit and MakeCode to realize ultrasonic distance measurement with URM09 Ultrasonic Sensor(Gravity Trig).
