Non-contact Small Diameter Pipe Liquid Level Sensor

Q: The indicator keeps on all the time.

1. The sensitivity is too high, please adjust it to a suitabe value.2. The init parameter is revised abnormally, in this case the sensor needs to be returned to the factory for restarting init.3. There are impurities or other metal objects contacted with the sensor closely, please clean the sensor and keep it away from any metal objects.

1. Example Code for Arduino-Liquid Level Detection

Detecting the liquid level of non-metallic containers,and check the status of sensor through serial port. Users can learn how to interface the non-contact liquid level sensor with Arduino and read digital signals to determine liquid presence.
