The module consists of an integrated ultrasonic sensor and control circuit. This product adopts industrial grade integrated ultrasonic probe design, waterproof type, stable performance and modest in the market. Some MCUs work.

1, Small size, easy to operate

2, wide power supply range, low power consumption

3, high measurement accuracy, high resolution

4, detection blind zone small, distance further away

5, the output mode diversified, pulse width output, serial port output.
