MQ-8 Sensor Information: sensitive material MQ- 8 gas sensors used in clean air, low conductivity tin oxide (SnO2). When there is an environment in which the combustible gas sensor, conductivity sensor with increasing concentration of combustible gases in air increases. Use simple circuit can convert the change in conductivity of the gas concentration corresponding to the output signal. MQ-8 hydrogen gas sensor of high sensitivity monitoring of other hydrogen-containing gas is also very good. The sensor can detect a variety of hydrogen-containing gas, in particular, city gas, is a low-cost sensor suitable for a variety of applications.
Suitable for home or industrial hydrogen leak monitoring devices. Can not interfere with ethanol vapor, soot, carbon monoxide and other gases.
Module Features: 1, using high-quality dual-panel design, with power indicator and a TTL signal output instructions; 2, with DO switching signal (TTL) output AO analog signal output; 3, TTL output valid signal is low. (When the output low signal light can be directly connected microcontroller or relay modules) 4, the higher the higher the voltage, the voltage concentration analog output. 5, for better hydrogen detection sensitivity. 6, there are four screw holes for easy positioning; 7, Product Dimensions: 32 (L) * 20 (the W) * 22 (H) . 8, has a long life and reliable stability 9, rapid response recovery characteristics
