SKU: SEN0376
This is DFRobot’s Gravity Alcohol Sensor (Arduino-compatible). It measures 0-5ppm alcohol concentration, supports I2C/UART, uses electrochemistry, is factory-calibrated, with strong anti-interference, high stability/sensitivity, 2-year lifespan, 0.01ppm resolution, 3.3-5.5V input. Works with Arduino/ESP32/Raspberry Pi, has Gravity interface and sample programs for easy detector building.
