MP-2 Flat Surfaced Smoke Gas Sensor

Household Smoke Gas Sensor

Applications :

*Domestic smoke leakage alarm, industrial smoke gas alarm and portable smoke detector.

Product Advantages:
  • *Good sensitivity to LPG, smoke in wide range
  • *Small size
  • *Long lifespan
  • *Low cost
  • *Simple circuit
Product Description:

MP-2 model with advanced planar construction is comprised of heater and metal oxide semiconductor material of subminiature Al2O3 ceramic plate, fetch out electrode down-lead, encapsulation in metal base and cap. When the target gas exists , the sensor’s conductivity is more higher along with the gas concentration rising. Please use simple electrocircuit, convert change of conductivity to correspond output signal of gas concentration.
