FIELD: biotechnology.
SUBSTANCE: group of inventions relates to analysers for determining the level of alcohol in air exhaled by a human body. Alcohol content sensor based on MEMS comprises a module for measuring alcohol content based on MEMS technology, an MCU processor, a circuit substrate and a housing. Alcohol content measurement module transmits the concentration signal to the MCU processor by means of a sampling and amplification circuit module, and the MCU processor processes the concentration signal and then outputs the alcohol concentration value.
EFFECT: high sensitivity and compactness of the device.
