Gravity: Analog Liquid Level Sensor (FS-IR02)

Photoelectric liquid's level sensor. It has high sensitivity without the need to use the mechanical parts. The probe withstands high temperature and high pressure. It works withthe Arduino modules. The kit includes a cable adapted to Gravity 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, includingArduino. To read data, simply connect the power supply and output pin to any input of the microcontroller, and read its status.
