Based on the electrochemistry principle, this alcohol sensor has been calibrated before the factory. It is characterized by strong anti-interference, high stability, and sensitivity and up to 2 years of service life. The module supports 0.01ppm(10ppb) resolution and 3.3~5.5V wide-range voltage input and works well with mainstream controllers like Arduino, ESP32, and Raspberry Pi. With the easy-to-use Gravity interface and the sample program provided by us, you can conveniently build your alcohol concentration detector using this sensor.
