MQ4 Methane Gas Sensor

Gas Detection: Primarily detects methane (CH4) and natural gas concentrations in the air.
High Sensitivity and Fast Response: Responsively detects even small changes in methane concentration.
Wide Detection Range: Can measure concentrations from approximately 200 parts per million (ppm) to 10,000 ppm.
Analog and Digital Outputs: Provides both types of outputs; the analog output gives a continuous voltage that correlates with the gas concentration, while the digital output switches when a threshold is reached.
