DFRobot Gravity Alcohol Sensor (0–5ppm) - I2C/UART Output
The DFRobot Gravity Alcohol Sensor is a low-power electrochemical gas sensor module designed for detecting alcohol vapor concentrations from 0 to 5 ppm. It features factory calibration, I2C and UART (0-3V) signal outputs, and is compatible with 3.3V/5V microcontrollers like Arduino, Raspberry Pi, and ESP32 for breathalyzer and air quality monitoring applications.
Features
- Electrochemical alcohol sensor with 0-5 ppm detection range
- Factory calibrated for accurate, stable readings
- Dual I2C and UART (0-3V) digital signal outputs
- Low power consumption (0.05W @ 5V) and wide 3.3-5.5V DC input
- Gravity interface for plug-and-play connectivity with DFRobot shields

This sensor employs an electrochemical sensing principle to detect alcohol (ethanol) vapor with high selectivity and sensitivity. Factory calibration ensures reliable, accurate concentration data in ppm, minimizing the need for user-side adjustment. The onboard signal conditioning provides stable, linearized outputs via I2C or UART interfaces.
Designed for integration into portable and fixed monitoring systems, it operates across a -20 to +50°C temperature range with anti-interference characteristics against common gases like benzene, toluene, and carbon monoxide. The module’s Gravity connector standard simplifies wiring for rapid prototyping and deployment in applications requiring precise alcohol concentration measurement.
