MQ-4 Gas Sensor Module resistors This load power supply canIntroduction: The gas sensing material used in the MQ 4 gas sensor is tin dioxide (SnO2) with low conductivity in clean air. It adopts high quality double panel design with power indication and TTL signal output indication It has DO switch signal (TTL) output and AO analog signal output 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) The voltage of the analog
