This propane gas sensor detects the concentrations of LPG, isobutane, and propane in the air and ouputs its reading as an analog voltage. The sensor can measure concentrations of 300 to 10,000 ppm.The sensor can operate at temperatures from -10 to 50°C and consumes less than 150 mA at 5 V.

Pinout Configuration:
For MQ-4 Sensor Module

Pin Name Description
VCC This pin powers the module, typically the operating voltage is +5V
GND Used to connect the module to system ground
Digital Out (DO) You can also use this sensor to get digital output from this pin, by setting a threshold value using the potentiometer
Analog Out (AO) This pin outputs 0-5V analog voltage based on the intensity of the gas
