Summary:

MP905 gas sensor is for air quality. 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. Conductivity of the sensor is affected by the concentration of target gas. The higher the concentration is, the higher conductivity of sensor gets. Users can adopt simple circuit to convert variation of conductivity into output signal corresponding to gas concentration.search and produce air quality monitoring gas sensor for household and office harmful gas detection, automatic exhaust device, air cleaner.

Feature:

* High sensitivity to benzene,toluene,formaldehyde,alcohol,smoke,lighter gas,paints

* Quick response and resume

* Low power consumption

* Simple detection circuit

* Excellent stability

APPLICATION

Indoor Air Quality Monitoring

The World Health Organization's "Indoor Air Pollution and Health" pointed out that the current level of indoor air pollution is 5-10 times higher than outdoor pollution, and 4% of global diseases are related to indoor air quality, and about 2 million people die prematurely each year from diseases caused by indoor air pollution.

Air Quality Monitor

Air pollution is becoming more and more serious. The value of PM2.5 (referring to particulate matter with aerodynamic equivalent diameter less than or equal to 2.5 microns in ambient air) is a parameter index.
