The Water Level Detection Sensor Module is a low-cost analog sensor that uses a comb pattern of nickel-plated traces to measure water level or detect the presence of liquid. It is a common choice for rain gauges, tank-level monitors and simple liquid-detection projects.
Key features:
- Analog Output: Produces a voltage that rises as more of the conductive traces are submerged, giving a graduated water-level reading.
- Corrosion-Resistant Traces: Nickel-plated exposed traces resist oxidation for more consistent long-term readings.
- Simple 3-Pin Interface: VCC, GND and analog signal (S) connect directly to any microcontroller’s analog input.
- Compact, Lightweight Board: A small PCB strip that mounts easily inside tanks, trays or drip pans.
- Low Power Draw: Draws only a small operating current, making it suitable for battery-powered projects.
- Wide Compatibility: Works with Arduino, ESP8266, ESP32 and other 3.3V-5V microcontroller boards.
