MQ-8 Hydrogen Gas Sensor Module
When there is the environment in which the combustible gas sensor, conductivity sensor increases with increasing concentration of combustible gases in air. The MQ-8 Hydrogen Gas Sensor Module H2 Alarm Detection uses a low conductivity tin oxide (SnO2).
A simple circuit is used to convert the change in conductivity of the gas concentration to the output signal. MQ-8 hydrogen gas sensor module of high sensitivity allow the monitoring of other hydrogen-containing gases as well.
It is a low-cost sensor that can detect a wide range of hydrogen gases, especially city gas.
This sensor is suitable for home or industrial hydrogen leakage monitoring devices. It is not affected by ethanol vapor, soot, carbon monoxide, or other gases.
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.
- Has a long life and reliable stability
- Rapid response and recovery characteristics
