Alcohol breath sensor

Alcohol breath sensor is a smart technology device used to detect the alcohol content in a person’s body. It plays a vital role in modern society, especially in the areas of road safety and public health. By detecting alcohol content in exhaled breath, the sensor can quickly and accurately determine whether a person has been drinking and assess their alcohol concentration level.
