MQ4 - Methane (CNG) Natural Gas Sensor ModuleThis MQ4 Methane Gas sensor module can sense the presence of compressed Natural Gas sensors (CNG), methane(CH4) etc. in the air. This is a very easy to use low cost semiconductor Gas sensor Module with analog and digital output. It requires no external components just plug in Vcc & ground pins and you are ready to go. It is small sensitive to alcohol and smoke. Specification Module MQ 4 Output Type Both Analog and Digital IC Chip LM393 Operating
