MQ-5 Gas Sensor (H2/LPG)
The MQ-5 Gas Sensor Module is a highly sensitive gas detection sensor designed to detect Hydrogen (H₂), LPG (Liquefied Petroleum Gas), Natural Gas, Methane (CH₄), and Town Gas. It is widely used in gas leakage detection systems, home safety devices, industrial monitoring equipment, and Arduino/Raspberry Pi projects.
The sensor features both analog and digital outputs, allowing easy integration with microcontrollers and embedded systems. Its onboard comparator enables adjustable sensitivity through a potentiometer, making it suitable for a wide range of gas detection applications.
