Using a semiconductor sensor for the concentration of alcohol vapors based on a microcontroller, the authors developed a device for monitoring the content of alcohol vapors with an indication of the readings on the LCD display. An algorithm for the work of the alcohol content control device developed by the authors is proposed. To take samples of exhaled air, a mouthpiece made by the authors was used. The results of full-scale tests of the developed instrument are given
