More info

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.

Features :

  1. Using high-quality dual-panel design, with 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 concentration of the analog output voltage is higher.
  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
