MQ2 Smoke LPG Gas Sensor Butane Hydrogen

Description:

• The sensor can detect H2, LPG, CH4, CO, Alcohol, Smoke, or Propane gasses and has the detection range of 300-10000ppm.
• The sensor employs a metal oxide semiconductor to measure gas concentrations and provides an analog output proportional to the gas levels.
• The sensor consists of a sensing element composed of a thin film of metal oxide, and as gasses are introduced to the sensor, they cause a change in the electrical conductivity of the metal oxide.
• This change is then measured and converted into an analog signal, providing the presence of gas concentration in the environment.

Specification:

• Operating Voltage:  5VDC
• Analog Output Voltage:  0V to 5V
• Digital Output Voltage 0V or 5V (TTL Logic)
• Dimensions in (mm): 36x20x21
• Weight (gm): 8

Package Includes:

1 x MQ2 Smoke LPG Gas Sensor Butane Hydrogen
