7Semi MQ-8 H2 Hydrogen Gas Sensor Breakout
The 7Semi MQ-8 H2 Hydrogen Gas Sensor Breakout is designed to detect hydrogen gas concentrations ranging from 100 to 10,000 ppm. It features a 3-pin JST connector for easy integration with microcontrollers and provides both analog and digital outputs. The sensor's high sensitivity and adjustable threshold make it suitable for applications like gas leak alarms and industrial monitoring systems.
Note
The sensor value only reflects the approximated trend of gas concentration in a permissible error range, it DOES NOT represent the exact gas concentration. The detection of certain components in the air usually requires a more precise and costly instrument, which cannot be done with a single gas sensor. If your project is aimed at obtaining the gas concentration at a very precise level, then we do not recommend this gas sensor.
Features
- Wide Detection Range: Detects hydrogen gas concentrations from 100-10,000 ppm.
- Easy Integration: Equipped with a 3-pin 2 mm pitch JST connector for quick and simple connection.
- Semiconductor Technology: Sensitive SnO2 material enhances accuracy in hydrogen detection.
- Analog & Digital Outputs: Provides both analog and digital signals for versatile application needs.
- Adjustable Sensitivity: Onboard potentiometer allows setting threshold gas concentrations.
- Low Cost & Long Lifespan: Durable and cost-effective solution for continuous monitoring.
