ZP01-MP503 air-quality module adopts flat surface semiconductor gas sensor. The module has very high sensitivity to volatile organic gases such as formaldehyde, benzene, carbon monoxide, ammonia, hydrogen, alcohol and smoke of cigarette, essence &etc. The module has been aging, debugged, adjusted and calibrated. So it has good consistency and high sensitivity.
Winsen Electronics, manufacture and provide ozone/ O3 gas sensor, based on the electrochemical principle, industrial and environmental protection fields.
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.
