ME007YS Waterproof Ultrasonic Distance Sensor

Q: ME007YS waterproof ultrasonic sensor does not work. There is no "FF" value. The output gives the garbage value.

When "RX" floats or input High level, the module outputs processed value, the data is more steady, response time: 100-300ms; when input Low level, the module outputs real-time value, response time: 100ms.<figure class="image"><img src="https://dfimg.dfrobot.com/628da052aa9508d63a41e164/makelog/7b7f5c95119f68484f8005b70e5ffa19_0x0.png.webp"></figure>

1. Example Code for Arduino-Measure Distance

This example use ME007YS ultrasonic sensor to measure distance. With initialization completed, We can get distance value.

2. Example Code for Raspberry Pi-Measure Distance

Connect board with raspberryPi. Run this demo. Connect ME007YS to UART to get the distance value.
