DFRobot Gravity: Non-contact Liquid Level Sensor

The sensor determines the liquid level without dipping into the liquid. Due to the lack of contact with the liquid, the module is suitable for level measurement of hazardous substances such as strong acid, bases, toxic substances and containers under high pressure. The sensor has 4 configurable sensitivity stages that are set using the SET button. It works withthe Arduino modules. The kit includes a cable adapted toGravity DFRobot IO Expansion Shield.

The product is compatible with Arduino

Sample code and detailed information can be found inthe user guide.

The module works with any microcontroller with digital inputs, including Arduino. To read data, simply connect the power supply and output pin to any input of the microcontroller, and read its status.
