Q & A

The MQ-5 Gas Sensor is a versatile semiconductor sensor designed to detect LPG (liquefied petroleum gas), natural gas, and town gas. It is commonly used in gas leak detection systems, industrial safety equipment, and home gas alarms.
The sensor features a SnO₂ (tin dioxide) sensing layer that changes resistance when exposed to combustible gases, producing a measurable analog signal proportional to gas concentration.
