This is a Winsen MP-5-24V C3H8 LPG Propane Flammable Gas Sensor Metal Cap. MP-5 gas sensor is for flammable gases. As an LPG gas sensor, It adopts multilayer thick film manufacturing technology. The heater and metal oxide semiconductor material on the ceramic substrate of subminiature Al2O3 are fetched out by electrode down-lead, encapsulated in metal socket and cap. The conductivity of the sensor is affected by the concentration of the target gas. The higher the concentration is, the higher conductivity of the sensor gets. Users can adopt a simple circuit to convert the variation of conductivity into an output signal corresponding to the gas concentration.

Features:

1.  Lower consumption
2.  Small size
3.  Fast response and resume
4.  Highest sensitivity
5.  Excellent stability and long life
6.  Easy circuit and big signal output

Package includes:

1 x MP-5 – 24V C3H8 LPG Propane Flammable Gas Sensor Metal Cap

The sensing element comprises a metal oxide semiconductor layer formed on the alumina substrate of a sensing chip together with an integrated heater. In the presence of detectable gas, sensor conductivity increases depending on gas concentration in the air. A simple electrical circuit can convert the change in conductivity to an output signal which corresponds to the gas concentration. The TGS2602 has high sensitivity to low concentrations of odorous gases such as ammonia and H2S generated from waste materials in office and home
environments. The sensor also has a high sensitivity to low concentrations of VOCs such as toluene emitted from wood finishing and construction products.
