Description

The MQ-3 Gas Sensor & Alcohol Detector Gas Sensor Module is a semiconductor-based sensing module primarily designed to detect alcohol vapors in the surrounding environment. Its sensing element changes electrical resistance according to the presence and concentration of detectable alcohol vapors, producing an electrical signal that can be monitored by a compatible microcontroller. The module provides analog and digital outputs, allowing users to monitor sensor variations or configure threshold-based detection using the onboard comparator and adjustable potentiometer. It can be connected to Arduino, ESP32, ESP8266, STM32, and other compatible development boards for experimental applications. The compact module is suitable for students, makers, hobbyists, and engineers learning about gas sensors, analog signals, environmental monitoring, and automation.

Features

LM393 Comparator: Enables convenient digital detection based on an adjustable threshold.
Adjustable Sensitivity: Onboard potentiometer allows users to configure the detection threshold.
Arduino Compatible: Can be easily integrated with Arduino-based gas-sensing projects.
Wide Platform Compatibility: Suitable for ESP32, ESP8266, STM32, and other compatible microcontrollers.
