A sensitive material, the MQ-8 Hydrogen Gas Sensor Module H2 Alarm Detection, is used in clean air with low conductivity tin oxide (SnO₂). When there is the environment in which the combustible gas sensor and conductivity sensor with increasing concentration of combustible gases in air increase.
Using a simple circuit to convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-8 hydrogen gas sensor of high sensitivity, the monitoring of the other hydrogen-containing gas is also very satisfactory.
This sensor can detect a wide range of hydrogen gas; city gas, in particular, is a low-cost sensor for a variety of applications.
Suitable for home or industrial hydrogen leakage monitoring devices. Cannot interfere with ethanol vapor, soot, carbon monoxide, and other gases.
Features:
1. Using a high-quality dual-panel design, with a power indicator and TTL signal output instructions.
2. The switching signal having a DO (TTL) output and analog output AO.
3. TTL output valid signal is low. (Low-level signal when the output light can directly connect to the microcontroller or relay module)
4. The higher the voltage, the higher the concentration of the analog output voltage.
5. A hydrogen gas detection with good sensitivity.
6. There are four screw holes for easy positioning.
7. Has a long life and reliable stability
8. Rapid response and recovery characteristics
Package Includes:
1 x MQ-8 Hydrogen Gas Sensor Module H2 Alarm Detection.
