Here is a tested Arduino project that uses 3 sensor probes as water level indicator with 3 leds and one LCD display + a simple controller that turns on a motor when the water has reached the desired ...

The following image shows the circuit diagram for interfacing the Contactless liquid level sensor with Arduino. Connections are pretty simple and only a few wires. Connect the VCC and GND of the ...

LEDs on the Arduino can be programmed to indicate if the sensor is/isn’t immersed by the liquid (and thus determine if liquid level is too high/low). The two companies say that the hardware provides ...
