Summary:

MR516 type gas sensor through gas absorption on the metal oxide semiconductor generates hot conduction and electronics conduction change principal, the white coil resistor change when detecting gas concentration. MR516 consists detecting element and compensation element, both elements are placed in a wheatstone bridge circuit, when the combustible gas appears, the detecting element resistor reduces, bridge circuit voltage output changes, the voltage will increase according to the gas concentration increase,the compensation element refers to temperature compensation

Feature:

* High sensitivity, large output                                                    
* Fast primary stability time, quick response 
* Remarkable reproducibility and reliability.                                                   
* Goode selectivity, avoid smoke ethanol disturb 
* Low consumption, miniature design

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.
