Description:

A sensitive material MQ-8 Hydrogen Gas Sensor Module H2 Alarm Detection used 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. This sensor can detect a wide range of hydrogen gas, city gas, in particular, is a low-cost sensor for a variety of applications.

Specification:

Main chip: the LM393, MQ-8 gas sensor

Working voltage: DC 5V

Power consumption ( current ): 150mA

DO output : TTL digital 0 and 1 ( 0.1 and 5V)

AO output: 0.1-0 .3 V ( relative to pollution ) the maximum concentration of a voltage of about 4V

Features:

Using a high-quality dual-panel design, with power indicator and TTL signal output instructions

The switching signal has a DO (TTL) output and analogue 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 analogue output voltage is higher

A 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

Application:

Suitable for home or industrial hydrogen leakage monitoring devices. Can not interfere with ethanol vapour, soot, carbon monoxide and other gases.
