Overview
In This Tutorial, I will show how you interface the Water Level Sensor With Arduino Nano Microcontroller And How You Write the Code.
Water Level Sensor
The water Level Sensor Has a series of parallel exposed traces to measure droplets/water volume in order to determine the water level.
The water level sensor is easy to monitor the water level as the output to analog signal Is Directly proportional to the water level.
The ADC Pin is Directly connected to the Arduino’s analog PIN.
Features:-
- Voltage:- DC 3-5v
- Current:- 20mA
- Sensor Type:- Analog
- Humidity:- 10% – 90%
Water Level Sensor Pinout
- VCC – 5v
- GND – GND
- Signal – A0
