Pinouts:

Pin Configuration:

Pin No: Pin Name: Description
For Module
1 Vcc Used to power the sensor, Generally the operating voltage is +5V.
2 Ground Used to connect the module to system ground.
3 Digital Out You can also use this sensor to get digital output from this pin, by setting a threshold value using the potentiometer.
4 Analog Out This pin outputs 0-5V analog voltage based on the intensity of the gas.
For Sensor
1 H -Pins Out of the two H pins, one pin is connected to supply and the other to ground
2 A-Pins The A pins and B pins are interchangeable. These pins will be tied to the Supply voltage.
3 B-Pins
  1. A pins and B pins are interchangeable. One pin will act as output while the other will be pulled to ground.
