Description:
The MQ-8 Hydrogen Gas Sensor Module is designed for detecting hydrogen gas (H₂) in the air with high sensitivity and stability. It operates using a tin dioxide (SnO₂) sensitive layer, which exhibits low conductivity in clean air. Upon exposure to hydrogen gas, the sensor's conductivity increases, and this change is converted into an electrical output signal for hydrogen detection and alert systems.
Features:
High sensitivity to Hydrogen (H₂)
Low sensitivity to alcohol, LPG, and cooking fumes
Reliable performance with stable output and long lifespan
Simple analog signal output for easy interfacing
Product Specification:
Sensitive Material: SnO₂ (Tin Oxide)
Gas Detection: Primarily Hydrogen (H₂); minor sensitivity to other gases
Operating Voltage: Typically 5V
Output Signal: Analog (voltage variation with gas concentration)
Preheat Time: 20 seconds to a few minutes for stable readings
Response Time: Rapid detection when hydrogen is present
Lifetime: Long service duration under standard operating conditions
Application:
Domestic and industrial hydrogen gas leak detection
H₂ safety monitoring in fuel cell systems
Hydrogen gas alarm systems
Fire and explosion prevention equipment
