Description
Overview:
- The gas sensing material used in the MQ-2B gas sensor is tin dioxide (SnO2) with lower conductivity in clean. When there is a flammable gas in the environment where the sensor is located, the conductivity of the sensor increases as the concentration of flammable gas in the increases. The change in conductivity can be converted to an output signal corresponding to the gas concentration using a simple circuit.
- The MQ-2B gas sensor is highly sensitive to propane and smoke and for the detection of natural gas and other flammable vapors. This sensor detects multiple flammable gases and a low-cost sensor for a wide of applications.
Characteristics:
This product has good sensitivity to propane, smoke, etc. in a wide concentration , and has the advantages of long life, low cost, and simple driving circuit.
Application:
Widely used in household gas leak alarms, industrial combustible gas alarms and portable gas detection instruments.
Basic Circuit:
The picture shows the basic test circuit for the MQ-2 sensor. The sensor requires two voltages to be applied: voltage (VH) and test voltage (VC). The VH is used to provide a specific operating temperature for the sensor, either DC or AC. The VRL is the voltage across the load resistor (RL) of the sensor in series. VC is the voltage for testing the load resistor RL and requires a DC power supply.
