GM-702B MEMS Carbon Monoxide Gas Sensor

Available:In Stock
R$ 56,90

Application:It is suitable for the detection of carbon monoxide leakage for residential use or industrial use.
Feature:MEMS technology, Strong construction,Small sizes and low power consumption,Fast response and resume

Production Description:
MEMS carbon monoxide gas sensor is using MEMS micro-fabrication hot plate on a Si substrate base, gas sensitive materials used in the clean air with low conductivity metal oxide semiconductor material. When the sensor exposed to gas atmosphere, the conductivity is changing as the detected gas concentration in the air. The higher the concentration of the gas, the higher the conductivity. Use simple circuit can convert the change of conductivity of the gas concentration corresponding to the output signal.
Feature:

  • MEMS technology, Strong construction
  • Small sizes and low power consumption
  • Fast response and resume
  • Simple drive circuit
  • High sensitivity to CO gas

Application:
It is suitable for the detection of carbon monoxide leakage for residential use or industrial use.
