About the Product
Description:
The MQ-4 Methane Gas Sensor is specifically designed for the detection of methane (CH4), the primary component of natural gas. It utilizes a Metal Oxide Semiconductor (MOS) type sensor, where the sensing material, tin dioxide (SnO2) doped with a catalyst, undergoes a change in electrical conductivity when exposed to methane or natural gas. The change in conductivity is then converted into an analog voltage output that corresponds to the concentration of the detected gas. The MQ4 offers good sensitivity to methane and is widely used in applications related to natural gas leak detection and monitoring.
Features:
- High Sensitivity to Methane and Natural Gas
- Good Sensitivity in a Wide Range
- Fast Response
- Stable and Long Lifespan
- Low Cost
- Simple Drive Circuit
