3pcs MQ-5 Liquefied Gas/Methane/Coal Gas/LPG Gas Sensor Module Shield Liquefied Electronic

Features Sensitive material MQ 5 gas sensor is used to clean the air in the lower conductivity of tin dioxide 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 5 gas sensor of high butane propane methane sensitivity methane and propane can be better taken into account This sensor can detect a variety of combustible gases especially natural gas is a low cost sensor for a variety of applications Suitable for home or industrial liquefied petroleum gas natural gas coal gas monitoring devices Excellent resistance to alcohol smoke 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 Electrical Performance
