Mq 4 Methane Natural Gas Sensor Module Shield Liquefied Electronic Detector For Arduino

Specification : - The gas sensing material used in the MQ-4 gas sensor is tin dioxide (SnO2) with low conductivity in clean air. - When there is a flammable gas in the environment where the sensor is located, the conductivity of the sensor increases as the concentration of flammable gas in the air increases. - A simple circuit can be used to convert the change in conductivity into an output signal corresponding to the gas concentration. - The MQ-4 gas sensor has high sensitivity to butane, propane and methane, and has a good balance between methane and propane. - This sensor detects a wide range of flammable gases, especially natural gas, and is a low cost sensor for a variety of applications. - Suitable for monitoring equipment for liquefied gases, natural gas and gas in the home or industry. Excellent resistance to ethanol and smoke. Features : 1. It adopts high quality double panel design with power indication and TTL signal output indication 2. It has DO switch signal (TTL) output Lees meer over de Mq 4 Methane Natural Gas Sensor Module Shield Liquefied Electronic Detector For Arduino van huismerk in de productgroep elektronica
