Water Level Sensor Module

A water level sensor module by ADIY can be used as a water level alarm. Easily interfaced with an Arduino or other microcontrollers, and read through Analog Input pins.ADIY Water level sensor is an easy-to-use, cost-effective solution to identifying the presence of water or any other conducting liquids. When the Water level sensor parallel conducting strips is dip in water or other conducting liquids a voltage is produced which is proportional to the level of the water. The voltage is directly read to analog input pins of the microcontroller board.

Features: Water Level Sensor Module

1. No moving parts.
2. Water-resistant enclosure.
3. Rugged design for long-term use.
4. Precise measurement.
5. Instantaneous results.
6. Output Voltage is proportional to liquid level.
7. Can Measure large changes in water level.
8. Low cost.

Water Liquid Level Sensor Pin Connections with microcontrollers

1. VCC ↔ 3.0V ~ 5.0V
2. GND ↔ power supply ground
3. AOUT ↔ MCU’s  I/O (analog output)

How It Works: Water Level Sensor Module

• The sensor has ten exposed copper traces, five of which are power traces and the remaining five
• are sense traces. These traces are interlaced so that there is one sense trace between every two power traces.
• Normally, power and sense traces are not connected, but when immersed in water, they are bridged.
• The more water the sensor is immersed in, the better the conductivity and the lower the resistance.
• The less water the sensor is immersed in, the poorer the conductivity and the higher the resistance.
• The sensor generates an output voltage proportional to the resistance; by measuring this voltage, the water level can be determined.
