MQ-8 Hydrogen Gas Sensor Module

Features:-

•     Using high-quality dual-panel design, with power indicator and TTL signal output instructions ;
•     The switching signal having a DO (TTL) output and analog output AO ;
•     TTL output valid signal is low . ( Low-level signal when the output light can directly connect to the microcontroller or relay module )
•     The higher the voltage, the concentration of the analog output voltage is higher.
•     A hydrogen gas detection with good sensitivity.
•     There are four screw holes for easy positioning ;
•     Product dimensions : 32 (L) * 20 (W) * 22 (H)
•     Has a long life and reliable stability
•     Rapid response and recovery characteristics

Applications:-

• Suitable for home or industrial hydrogen leakage monitoring devices. Can not interfere with ethanol vapor, soot, carbon monoxide and other gases.

Specifications:-

• Input voltage : DC5V Power consumption ( current ): 150mA
• DO output : TTL digital 0 and 1 ( 0.1 and 5V)
• AO output: 0.1-0 .3 V ( relative to pollution ), the maximum concentration of a voltage of about 4V
