Hydrogen Gas Sensor

Description

This is a simple-to-use hydrogen gas sensor, suitable for sensing hydrogen concentrations in the air. The MQ-8 can detect hydrogen gas concentrations anywhere from 100-10000ppm.

This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance. The drive circuit is very simple; all you need to do is power the heater coil with 5V, add a load resistance, and connect the output to an ADC.

Features:

  1. Main chip: the LM393

  2. working voltage: DC 5V

  3. Analog 0 ~ 5 v voltage, the higher the concentration, the higher the voltage.

  4. Very sensitivity to hydrogen

  5. Can be resistant to ethanol steam, LPG (petroleum), smoke interference

  6. Has a long service life and reliable stability

  7. Has quick response recovery features
