WATER LEVEL SENSOR
The water level sensor is a critical component of the water level indicator project. It is designed to detect water levels and provide an output based on the resistance of the water present in the tank. The sensor consists of a series of parallel exposed conductors, acting as a variable resistor. When submerged in water, the sensor’s resistance changes, allowing it to indicate different water levels.

General Description:
The water level sensor is a critical component of the water level indicator project. It is designed to detect water levels and provide an output based on the resistance of the water present in the tank. The sensor consists of a series of parallel exposed conductors, acting as a variable resistor. When submerged in water, the sensor’s resistance changes, allowing it to indicate different water levels.
Working Principle:
The sensor operates based on the principle of variable resistance. As more water is present in the tank and the sensor is submerged, the conductivity increases, leading to lower resistance. Conversely, less water results in higher resistance. The sensor’s analog output is proportional to the resistance, allowing you to determine the water level.
Specifications:
1. The operating voltage range is 3 to 5 volts DC.
2. Maximum operating current is 20 mA.
3. The detecting range of the sensor is 40 x 16 mm.
4. The sensor type is Analog.
5. Operating temperature ranges from -10 to 30 °C.
6. Humidity range tolerated is 10% to 90% non-condensing.
7. Length measures 60 mm, width 20 mm, and height 1.5 mm.
