DFRobot Gravity Steam Sensor - Analog Output Module
The DFRobot Gravity Steam Sensor is an analog humidity detection module compatible with 3.3V and 5V logic systems, including Arduino, Raspberry Pi, and ESP32. It outputs a variable voltage signal proportional to the moisture level on its sensing surface.
Features
- Analog voltage output scales with surface humidity (0-4.5V @5V, 0-3.0V @3.3V)
- Wide operating voltage range from 3.3V to 5V DC
- Plug-and-play compatibility with DFRobot Gravity 3-pin interface and Arduino shields
- Compact PCB design measuring 30mm x 20mm
- Simple threshold-based detection for steam, condensation, or liquid contact

The DFRobot Gravity Steam Sensor operates on a resistive sensing principle, where changes in surface conductivity due to moisture alter the output voltage. The module includes onboard signal conditioning to provide a clean, stable analog signal directly readable by a microcontroller’s ADC pin.
Designed for educational and prototyping environments, this sensor offers a straightforward method for detecting the presence of steam, water droplets, or high humidity. Its Gravity-standard 3-pin connector simplifies wiring and integration into rapid development workflows.
