Winsen MP-2 Smoke & Propane Gas Sensor Module - Semiconductor Metal Cap
The Winsen MP-2 is a semiconductor-type gas sensor module designed for detecting smoke and propane (C3H8) vapors, providing a variable analog output voltage proportional to gas concentration. It is suitable for integration into DIY alarm systems, industrial monitoring, and portable detectors compatible with 3.3V/5V microcontroller platforms like Arduino and Raspberry Pi.
Features
- Semiconductor sensing element with Al2O3 ceramic substrate for smoke and propane (C3H8) detection
- Wide detection range from 200 ppm to 10,000 ppm of C3H8
- Analog output voltage signal (Vs) ranging from 2.5V to 4.0V in 2000ppm C3H8
- Metal cap encapsulation ensures mechanical durability and stable thermal performance
- Simple interface requiring only a basic voltage divider or comparator circuit for integration

The Winsen MP-2 sensor utilizes a metal oxide semiconductor (MOS) sensing principle. Its construction features a miniature Al2O3 ceramic plate coated with sensitive material, a built-in heater, and electrodes, all housed within a protective metal cap and base. When exposed to target combustible gases like propane or smoke particulates, the sensor’s conductivity increases proportionally with gas concentration. This change in conductivity can be converted into a corresponding analog output voltage signal using a straightforward external circuit.
Designed for reliability and long-term operation, the MP-2’s planar technology and robust metal encapsulation provide consistent performance across its operational lifespan. It is a core component for creating gas-aware safety systems, requiring minimal supporting electronics to generate a usable alarm or measurement signal.
