MQ-5 Natural/ LPG Gas Sensor Module for Arduino
Features
Small sensitivity to LPG, H2, LPG, CH4, and CO
Fast response
Stable and long life
Simple drive circuit
Indication of the signal output.
Dual signal output (analog output, and TTL level output)
TTL output signal is low. (When low output signal light, and can be connected directly to the microcontroller)
Liquefied petroleum gas, natural gas, city gas, better sensitivity.
Has a long life and reliable stability

Pinouts of MQ5 Sensor
Pin Name Description
Vcc Power Pin requires an operating voltage of 5V.
GND Ground pin.
DO Digital out the pin, to get the digital output from the sensor, need to set the threshold value using Pot.
AO Analog out the pin. It based the output of this pin on the intensity of the methane gas.
