Winsen MP-3B Alcohol Gas Sensor Module - Semiconductor, Metal Cap
The Winsen MP-3B is a semiconductor-based alcohol gas sensor module designed for breathalyzer and ethanol vapor detection applications. It operates on a simple drive circuit, converting changes in conductivity into a corresponding output signal for gas concentration measurement.
Features
- Semiconductor sensing element with planar Al2O3 ceramic plate construction
- Target gas: Alcohol (Ethanol) with a detecting range of 0-500 ppm
- Low heater consumption ≤350mW for reduced power requirements
- Metal cap encapsulation ensures durability and stable performance
- Simple interface requiring only a basic voltage divider circuit for signal output

The Winsen MP-3B alcohol gas sensor employs a metal oxide semiconductor (MOS) sensing principle. Its construction features a miniature Al2O3 ceramic substrate coated with a sensitive material, a micro-heater, and electrodes, all housed within a protective metal cap. When exposed to alcohol vapor, the sensor’s conductivity increases proportionally with the gas concentration, allowing for detection through a straightforward external circuit.
This module is engineered for reliable performance in detecting ethanol steam, offering fast response and recovery times alongside excellent long-term stability. Its compact form factor and low power consumption make it suitable for integration into portable or fixed-point monitoring systems.
