Was: 3.88
Price: 3.23

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 sensors 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 response recovery characteristics El
