MP135-type air pollution detection elements in a plane semiconductor gas (air pollution sensor, air quality sensor) plane advanced production technology, in the micro-Al2O3 is formed on the ceramic substrate and the metal oxide semiconductor gas heater material, with the electrode wire leads, packaged in a metal tube holder, tube cap. When there is detected the presence of gas, the gas concentration in the air is higher, the higher the conductivity of the sensor. Using a simple circuit can be converted to the change of conductivity with the output signal corresponding to the gas concentration.

Application:
For a family environment and hazardous gas detection automatic exhaust devices, air cleaners and so on.

Provide a reference routines, circuit diagrams and instructions, contact after the arrival of mail.

 

Package Included:

1 pcs x MP-135 gas detection sensor
