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 air increases. The change in conductivity can be converted to an output signal corresponding to the gas concentration using a simple circuit.- The MQ-4B methane sensor has high sensitivity to methane and strong anti-interference ability to alcohol and other disturbing gases.;Characteristics:;This product has good sensitivity to methane in a wide concentration range, 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 detectors;Basic Circuit:;;;;; ; ;The figure above shows the basic test circuit for the MQ-4B sensor. The sensor requires two voltages to be applied: heater 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. €Š €ŠPackage Included: €Š €Š1 x;MQ-4B
