The MQ-3 gas sensor module is a highly sensitive and reliable detector for alcohol, ethanol, and benzene vapor in the air. It is an essential tool for electronics hobbyists, students, and developers working on safety, health, or educational projects.

Key Features:

High Sensitivity: Effectively detects concentrations of alcohol vapor.
Easy Integration: Operates at a standard 5V DC, making it compatible with popular development boards like Arduino, ESP8266, ESP32, and Raspberry Pi.
Dual Output: Provides both analog output (for precise concentration readings) and digital output (for threshold-triggered switching).
Adjustable Threshold: The onboard potentiometer allows easy calibration of the digital output's sensitivity.
Wide Range of Applications: Ideal for building DIY breathalyzers, air quality monitoring systems, vapor leak alarms, or educational science projects.

Project Ideas: Build your own breathalyzer, a car safety interlock system, a smart lab monitor, or an engaging educational demonstration about gas sensors.

The perfect choice for anyone looking to add reliable gas detection capabilities to their next innovative project!

Size: approx. 32 x 22 x 27mm

Main chip: LM393, ZYMQ-3 gas detector

Working Voltage: DC 5V

With signal output instructions.

Two-way signal output (TTL level output and analog output).

TTL output effectively signal for low level(when the output low level signal lights, can directly connected microcomputer).

Analog output 0 ~ 5v voltage, the higher the concentration, the higher the voltage.

Has a high sensitivity and good selectivity.

Has long service life and reliable stability.

Rapid response recovery features.

For motor vehicles and other prohibition drunken drivers homework personnel on-site testing, also used in other places of ethanol vapor detection.
