Key Features
- High Sensitivity Detection: Exposed parallel copper traces detect water contact as shallow as 1mm, providing reliable early-warning capability for leaks and rising water levels.
- Analog Output for Precise Readings: Outputs a continuous analog voltage proportional to the depth of water covering the sensor traces, enabling accurate level measurement - not just on/off detection.
- Wide Voltage Compatibility (3.3V-5V): Works seamlessly with both 3.3V platforms (ESP32, STM32) and 5V platforms (Arduino Uno, Mega) without any level shifting required.
- Simple 3-Pin Interface: Standard S/VCC/GND pinout connects directly to any Arduino analog input pin - no external pull-up resistors, amplifiers, or signal conditioning needed.
- Compact & Lightweight Design: At just 62mm x 20mm and 3g, the sensor fits into tight enclosures, small tanks, and portable weather stations without adding bulk.
- Breadboard & Dupont Friendly: 2.54mm pitch header pins plug directly into breadboards or accept standard Dupont jumper wires for rapid prototyping.
- Fast Response Time: Sub-second response ensures your system reacts immediately to changing water conditions - critical for flood alerts and overflow prevention.
- Low Power Consumption: Draws less than 20mA, making it suitable for battery-powered and solar-powered IoT deployments.
- M3 Mounting Hole: Built-in mounting hole allows secure, vibration-resistant installation inside tanks, sumps, or outdoor enclosures.
- Corrosion Management: Sensor longevity can be significantly extended by powering the sensor only during readings (using a digital GPIO pin to control VCC), reducing electrolysis of the copper traces.
