【SEN0312】ME007YS Waterproof Ultrasonic Sensor FAQ
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.
