- 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;
- A 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.
The MQ-8 gas sensor module is a device that can detect the presence of hydrogen gas in the air. It is commonly used in applications such as gas leak detectors, safety devices, and industrial control systems. The MQ-8 sensor operates by using a chemical reaction between the hydrogen gas and a conductive metal oxide to produce a current. The magnitude of the current is proportional to the concentration of hydrogen gas in the air. The sensor can be used to detect hydrogen gas concentrations in the range of 100-10000 ppm.
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. Can not interfere with ethanol vapor, soot, carbon monoxide, and other gases.
Applications:
- Detect leakages in the industry
- Used in mines
- Can be used in refrigerators and AC
