Water Level Sensor Module

The Water Level Sensor Module detects the presence and level of water using a series of exposed conductive traces. As water touches more traces, the sensor output changes, allowing microcontrollers like Arduino Uno R3 and ESP32 Development Board to estimate the water level.

The sensor provides:

• Analog output for water level measurement
• Digital output (on some versions) for threshold detection

It is widely used in:

• Water tank monitoring
• Rainwater systems
• Smart irrigation
• Liquid level alarms
