Water Level Sensor
The Water Level Sensor uses exposed conductive traces to detect liquid levels in tanks and containers. It provides an analog output proportional to immersion depth for overflow prevention, automated pumping, and liquid level monitoring.
Key Features
- Multi-level detection via exposed conductive traces
- Analog output proportional to water level
- Multiple detection zones on single sensor strip
- Compact design for narrow tank installation
- Low power consumption suitable for continuous monitoring
- 3.3V-5V operation compatible with all microcontrollers
- Easy mounting with screw holes

Applications
- Tank level monitoring and overflow prevention
- Automated pumping systems
- Aquarium water level maintenance
- Reservoir management
- Industrial liquid level control
- Smart irrigation systems
Important Notes
- Sensor must be mounted vertically for proper level detection
- Clean sensor surface regularly to prevent mineral buildup
- For corrosive liquids, use isolated/protected sensor variants
- Not for use with distilled/deionized water (non-conductive)
- Analog readings vary with water conductivity – calibrate for your application
