MP905 Air-Quality Gas Sensor

Available:In Stock
R$ 34,90

Application:It is used in occasions such as household and office for harmful gas detection, automatic exhaust device, air cleaner etc.
Feature:High sensitivity to benzene,toluene,formaldehyde,alcohol,smoke,lighter gas,paints;quick response and resume;

Production Description:
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.
Feature:

  • High sensitivity to benzene,toluene,formaldehyde,alcohol,smoke,lighter gas,paints;quick response and resume;
  • Low power consumption, simple detection circuit, good stability and long life.

Application:
It is used in occasions such as household and office for harmful gas detection, automatic exhaust device, air cleaner etc.
