Flat Semiconductor Combustible Gas Sensor MP-2

Summary:

MP-2 model with advanced planar construction is comprised of heater and metal oxide semiconductor material of subminiature Al₂O₃ ceramic plate, fetch out electrode down-lead, encapsulation in metal base and cap. When the target gas exists , the sensor's conductivity is more higher along with the gas concentration rising. Please use simple electrocircuit, convert change of conductivity to correspond output signal of gas concentration.

Feature:

* Good sensitivity to LPG, smoke in wide range

* Small size

* Long lifespan

* Low cost

* Simple circuit

APPLICATION

Home Combustible Gas Alarm

The combustible gas alarm is an alarm device for detecting gas leakage. The component that reacts to the combustible gas is a gas sensor, and the response signal is converted into an electrical signal through the circuit board. When the combustible gas in the air reaches a certain concentration value, the alarm will alarm. The high-end household combustible gas alarm can automatically start the exhaust equipment and close the gas pipeline valve at the same time. A wireless transmission device can be installed inside the gas alarm to realize overall monitoring and network alarm to ensure the safety of everyone's life and property.
