Alcohol Gas Sensor MQ-3
The MQ-3 is a semiconductor gas sensor that detects alcohol vapour at concentrations from 0.04 mg/L to 4 mg/L — a range suitable for building a breathalyser. It provides a simple analog voltage output that requires only one analog input pin from your microcontroller.
Key Features
- Alcohol Detection Range – 0.04 to 4 mg/L
- Analog Output – Simple voltage interface, one ADC pin required
- High Sensitivity – Suitable for breathalyser applications
Ideal For
- Breathalyser projects
- Air quality and gas detection
- Arduino and microcontroller sensor projects
Package Contents
- 1× MQ-3 alcohol gas sensor
