Description:
The MQ-8 Hydrogen Gas Sensor Module is a highly sensitive sensor designed for detecting Hydrogen (H2) gas in various environments. It operates using a SnO2 (Tin Oxide) sensitive material, which exhibits low conductivity in clean air. When exposed to combustible gases, the sensor’s conductivity increases in proportion to the concentration of gases present. The MQ-8 is ideal for hydrogen gas leak detection in both home and industrial settings. Its analog output and TTL digital output make it compatible with a wide range of microcontroller and relay systems.
High Sensitivity: Detects hydrogen gas and other hydrogen-containing gases with great sensitivity.
Dual-Panel Design: Features both analog output (AO) and TTL digital output (DO) for flexible integration.
Low-Level Signal Output: TTL output provides a low-level signal that can be easily interfaced with microcontrollers or relay modules.
Quick Response & Recovery: Rapid response to hydrogen gas and quick recovery after detection.
Non-Interference: Does not detect ethanol vapor, soot, carbon monoxide, or other gases, ensuring accuracy.
Long Life & Stability: Designed for durability and long-term use in monitoring devices.
Easy Mounting: Four screw holes included for easy positioning and installation.
Operating Voltage: 5V DC
Output Types: Analog (AO) and Digital (DO)
Material: Tin Oxide (SnO2)
Sensitivity: High sensitivity to hydrogen gas (H2)
Applications: Ideal for hydrogen gas leak detection in both home and industrial environments.
VCC: Positive pole (5V)
GND: Negative pole
DO: TTL signal output (digital, low-level)
AO: Analog output (concentration-based)
Hydrogen Leak Detection: Suitable for monitoring hydrogen gas leaks in industrial and home environments.
Safety Systems: Can be used in safety devices to prevent gas leaks and ensure safety.
Hydrogen Containment Monitoring: Ideal for applications where hydrogen storage or use is involved.
Product specifications may be updated from time to time, and the actual product may vary slightly in terms of color or design.
