MQ-8 Hydrogen Gas Sensor Module H2 Alarm Detection

A sensitive material MQ-8 Hydrogen Gas Sensor Module H2 Alarm Detection use in clean air low conductivity tin oxide (SnO2). When there is the environment in which the combustible gas sensor, conductivity sensor with increasing concentration of combustible gases in air increases. 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.

Specifications

  • With a signal output instructions.
  • Dual signal output (TTL level output and analog output)
  • TTL output valid signal for low level.
  • Analog 0 ~ 5 v voltage, the higher the concentration, the higher the voltage.
  • High sensitivity to hydrogen
  • Can be resistant to ethanol steam, LPG (petroleum), smoke interference
  • Has a long service life and reliable stability
  • Quick response recovery features

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.
  • 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

Package Content:

1 x MQ-8 Hydrogen Gas Sensor Module H2 Alarm Detection
