Principle:

The gas sensing material used in the MQ-5 gas sensor is tin dioxide with low conductivity in clean air. When there is flammable gas in the environment where the sensor is located, the conductivity of the sensor increases with the increase in the concentration of flammable gas in the air. big. External oscillator resistance 100K~240KΩ (the larger the resistance, the slower the sound speed), the buzzer can be driven to sound after power-on. Pin 1 is grounded, pin 2 is output, pin 3 is the sound terminal, pin 4 is connected to the positive pole of the power supply, and pins 5 and 6 are connected to the shock resistance.
