MQ2 Gas Sensor - Working Principle & Its Applications

· MQ2 gas sensor is an electronic sensor used for sensing the concentration of gases in the air such as LPG, propane, methane, hydrogen, alcohol, smoke and carbon monoxide. MQ2 gas sensor is also known as chemiresistor. It contains a sensing material whose resistance changes when it comes in contact with the gas. This change in the value of resistance is used for the detection of gas. MQ2 …

Understanding a Gas Sensor | Jaycon Systems

· This resistor serves to adjust the sensor’s sensitivity and accuracy. The value can range anywhere from 2k Ohms to 47k Ohms. The higher the value, the more sensitive the sensor becomes. The value depends on whether you want to measure high concentrations of gas or not. If you choose to measure high concentrations of gas, but choose a high value for the load resistor, then the readings …
