Guide for MQ2 Gas Sensor with Arduino | Random Nerd …

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 ...


Gravity: Analog CO2 Gas Sensor For Arduino (MG811 Sensor ...

This CO2 Sensor Arduino is able to detect the carbon dioxide. It uses MG811 probe to detect CO2. The output voltage of the module falls as the concentration of the CO2 increases. Come to know more about the price and spec of the analog CO2 gas sensor.

Sensors — Arduino Official Store

The sensor traces have a weak pullup resistor of 1 MΩ. The resistor will pull the sensor trace value high until a drop of water shorts the sensor trace to the grounded trace. Believe it or not this circuit will work with the digital I/O pins of your Arduino or you can use it with the analog pins... View full details


Guide for MQ2 Gas Sensor with Arduino | Random Nerd Tutorials

May 05, 2016· Example: Gas Sensor with Arduino. In this example, you will read the sensor analog output voltage and when the smoke reaches a certain level, it will make sound a buzzer and a red LED will turn on. When the output voltage is below that level, a green LED will be on. Parts needed: So, for this example, you’ll need: 1 x MQ2 gas sensor
