Product description
MQ-8 hydrogen (H₂) sensor. The sensitive material in the MQ-8 gas sensor is SnO₂, which has low conductivity in clean air. When the target gas is present, the sensor’s conductivity increases in proportion to the gas concentration. A simple electronic circuit can be used to convert this change in conductivity into a corresponding output signal that represents the gas concentration.
The sensor can be mounted on a suitable breakout board 41004066.
Specifications:
- High sensitivity to hydrogen (H₂)
- Adjustable sensitivity
- Drivspänning: 5 V
- Power consumption: 900 mW, the sensor becomes warm during operation
- Detection range: 100–1000 ppm
- Dimensions: Ø19.5 × 24 mm, including pins
Applications:
- Hydrogen leak detection in laboratories, test environments, and research facilities
- Safety systems in hydrogen-based energy systems, for example fuel cells and electrolysis
- Monitoring of hydrogen in battery charging environments, lead-acid batteries can emit H₂ during charging
- Industrial applications where hydrogen is used or produced
- Education, prototyping, and development projects in sensor technology and gas detection
