MQ-8 H2 Gas Sensor Module Shield Liquefied Electronic Sensor Module

Features MQ 8 gas sensor sensitive material used in clean air conductivity is lower tin dioxide SnO2 When the sensor is present in the environment in which the combustible gas the sensor s conductivity increases with the concentration of combustible gases in air increases Using a simple circuit can be converted to the change in conductivity of the gas concentration with the corresponding output signal MQ 8 H2 gas sensor of high sensitivity the monitoring of the other hydrogen containing gas is also very satisfactory The sensor can detect a variety of hydrogen containing gas in particular city gas is a low cost sensors for a variety of applications Suitable for domestic or industrial H2 leak on a monitoring device Are not subject to ethanol vapor soot carbon monoxide and other gases interference Speciffications 1 It adopts high quality double panel design with power indication and TTL signal output indication 2 It has DO switch signal TTL output and AO analog signal output 3 The TTL output valid signal is low When the output is low the signal light is on it can be directly connected to the MCU or relay module 4 The voltage of the analog output the higher the concentration the higher the voltage 5 It has good sensitivity to gas and natural gas detection 6 there are four screw holes for easy positioning 7 product dimensions 32 L 20 W 22 H 8 has a long service life and reliable stability9 fast resp0nse recovery characteristics E
