With its high sensitivity and rapid response times, this kit-based device, utilizing the MQ-3 sensor, accurately detects the quantity of alcohol vapors in the breath, providing timely alerts both visually, through LEDs, and audibly with a sound alarm.

When combined with an alarm system, this kit can be used indoors to detect the presence of various gases, LPG, gasoline aerosols, and alcohol, activating a relay as needed. Onboard, there is a trimmer for adjusting the sensor's sensitivity.

The device operates on a 5VDC voltage and can be powered via a wall adapter or car cigarette lighter plug (not included, see related products).

Soldering is required for assembly. Instructions are included and are available in English.
