23/6/2015· LPG gas sensor module''s DO pin is directly connected to pin 18 (A4) of Arduino and Vcc and GND are connected to Vcc and GND of arduino. LPG gas sensor module consist a MQ3 sensor which detects LPG gas. This MQ3 sensor has a heater inside which needs some heater supply to heat up and it may takes up to 15 minute to get ready for detecting LPG gas.

6/5/2016· What is an MQ2 Smoke Sensor? The MQ2 smoke sensor is sensitive to smoke and to the following flammable gases: LPG; Butane; Propane; Methane; Alcohol; Hydrogen; The resistance of the sensor is different depending on the type of the gas. The smoke sensor has a builtin potentiometer that allows you to adjust the sensor sensitivity according to how accurate you want to detect gas.

Hooking up an MQ2 (gas smoke) sensor to an Arduino Uno via a breadboard. The wiring connection is important: Both A pins and the left H pin need to be connected to 5V. Both B pins need to be connected to the analog input (A0). The right H pin needs to be connected to the ground (GND). A load resistor from 2kOhm to 47kOhm needs to be ...
