Description

Specifications & Features of MQ8 Hydrogen H2 Gas Sensor Module:-
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)
Analog 0 ~ 5 v voltage, the higher the voltage, the concentration of the analog output voltage is higher.
Continuous analog output.
A hydrogen gas detection with good sensitivity.
There are four screw holes for easy positioning.
Has a long life and reliable stability
Rapid response and recovery characteristics
