MQ8 Hydrogen H2 Gas Sensor Module
Description:
MQ8 Hydrogen Gas Sensor Module is a sensitive gas detection module specifically designed to detect Hydrogen (H₂) gas in the air. It is built around the MQ8 semiconductor sensor, which offers high sensitivity and fast response to Hydrogen gas while having low sensitivity to other gases. The MQ8 sensor is widely used in various safety systems, industrial processes, and portable gas detectors.Module outputs both analog and digital signals, making it easy to interface with microcontrollers like Arduino, Raspberry Pi, and other development platforms for real-time Hydrogen gas monitoring applications.
Features:
1. High sensitivity to Hydrogen (H₂) gas
2. Dual output: Analog voltage output & Digital output
3. Fast response and recovery time
4. Adjustable sensitivity via onboard potentiometer
5. Long life and low cost
6. Easy to interface with microcontrollers
7. Suitable for indoor and outdoor applications
8. Onboard LM393 comparator for digital output switching
9. LED indicators for power and output status
