Alcohol Gas Concentration Sensor High Sensitivity Breathalyzer Module Vehicle Detection DIY Projects

Alcohol Gas Concentration Sensor High Sensitivity Breathalyzer Module Vehicle Detection DIY Projects Description

Alcohol sensor module with a measuring range of 0-5ppm, supporting I2C and UART outputs.
Fast and accurate detection of alcohol gas concentration in the air, ideal for breathalyzers and vehicles.
Calibrated at the factory based electrochemistry principles, ensuring reliable performance.
Wide operating voltage of 3.3~5.5V and low power consumption of 0.05W (5V).
Interfering gases include benzene, toluene, acetic acid, hydrogen sulfide, and carbon monoxide; with a service life of over 2 years in the air.

This is an compatible alcohol sensor module aiming at fast and accurate detection of alcohol gas concentration in the air. The sensor is well applicable to the small alcohol concentration measurement in breathalyzers, vehicles, and more. The module supports 0.01ppm (10ppb) resolution and works well with mainstream controllers like , ESP32, and Raspberry Pi.
