Fig2. MQ131 Test Circuit Instructions: The above fig is the basic test circuit of sensor requires two voltage inputs: heater voltage (V H) and circuit voltage (V C). V H is used to supply standard working temperature to the sensor and it can adopt DC or AC power, while V RL is the voltage of load resistance R L which is in series with
