20160509· Understanding a Gas Sensor. Gas Sensor. Gas sensors serve to measure the concentration of gases in the environment. There are many different types depending on what you want to measure. In this case, the MQ4 gas sensor can measure Liquefied Petroleum Gas (LPG), Methane (CH4), Hydrogen (H2), Carbon Monoxide (CO), alcohol, and smoke concentrations.

20181007· 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 05V analog voltage based on the intensity of the gas. For MQ3 Sensor. 1. H Pins. Out of the two H pins, one pin is connected to supply and the other to ground . 2. APins. The A pins and B pins are interchangeable. These ...

Gas sensor MQ4 registers the presence and concentration of natural gas and methane (CH4). The best results are given when gas is in liquid form, however, since situations like this are rare, it does its job pretty well when in gas form, too. It needs a bit of time to warm up in order to work correctly. • Detects: natural gas and methane• Dimensions: 32mm x 22mm x 27mm• Voltage: 5V ...
