The MQ-4 Natural Gas Sensor Module detects compressed natural gas (CNG), methane (CH4), and other combustible gases. It features both analog and digital outputs, an onboard LED indicator, and a potentiometer to set the digital trigger threshold. The module uses the MQ-4 sensor with a detecting range of 300 to 10000 ppm and operates at 3-5V DC. It is ideal for domestic gas leakage detectors, industrial combustible gas detectors, and portable gas detectors.
