MQ-8 Hydrogen Gas Sensor Module
MQ-8 is a Metal oxide semiconductor (MOS) type sensor from the series of MQ gas sensors (MQ-2, MQ-3, MQ-4, and so on). The module is highly sensitive to Hydrogen gas and can be used to detect any leaks or presence of Hydrogen gas in the air.
Features
- High sensitivity to hydrogen gas (H₂).
- Detects hydrogen concentrations ranging from 100 to 10000ppm.
- Provides both analog and digital output signals.
- Fast response and recovery times for timely detection.
- Simple drive circuit for easy implementation.
- Long service life with stable performance.
- Adjustable sensitivity via onboard potentiometer.
- Compact design suitable for various applications.
