Development of Single Chip Microcomputer for Breathing Alcohol Tester

Breath alcohol tester is a unique and mature breath alcohol concentration tester. The breath alcohol tester uses the change of the sensor’s semiconductor electrical characteristics to detect the alcohol concentration. It uses a self-developed new ceramic material and catalytic technology to analyze the alcohol concentration in the breath with high selectivity. The sensor only reacts with alcohol, unlike Other general-purpose semiconductor sensors are equally susceptible to interference from many other gases (such as smoking and the smell of food).

Features of breath alcohol tester
