May 06, 2016· The MQ2 smoke sensor is sensitive to smoke and to the following flammable gases: 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.
Ardunio Smoke and Gas Sensor(MQ2): Hello everyone , I have got another super easy arduino tutorial, this time is on the MQ2 gas and smoke detector. Mostly combustible gases, propane and very easy to connect and program. Just using the map function.
Structure and configuration of MQ2 gas sensor is shown as Fig. 3, sensor composed by micro AL2O3 ceramic tube, Tin Dioxide (SnO2) sensitive layer, measuring electrode and heater are fixed into a crust made by plastic and stainless steel net. The heater provides necessary work conditions for work of sensitive components.
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.
MQ 2 Gas Sensor The MQ 2 gas sensor is used to detect or monitor the concentration and/or presence of combustible gases in the air. It features a simple drive circuit, stable, long life, fast response, and a wide Due to its high sensitivity to hydrogen, LPG (liquid petroleum gas), methane,
Feb 07, 2020· MQ2 Gas Sensor Module is a smoke sensitive product detecting flammable gases such as Methane, Butane, Propane, Alcohol, and series of MQ smoke sensors come with a small heater inside along with an electrochemical sensor. MQ2 gas sensor is capable of detecting a range of gases with gas concentrations anywhere from 200 to 10000ppm and is feasible for indoor applications …
Jan 17, 2018· The smoke sensor we will use is the MQ2. This is a sensor that is not only sensitive to smoke, but also to flammable gas. The MQ2 smoke sensor reports smoke by the voltage level that it outputs. The more smoke there is, the greater the voltage that it outputs. Conversely, the less smoke that it is exposed to, the less voltage it outputs.
Jan 04, 2018· The MQ2 Gas sensor can detect or measure gasses like LPG, Alcohol, Propane, Hydrogen, CO and even methane. The module version of this sensor comes with a Digital Pin which makes this sensor to operate even without a microcontroller and that comes in handy when you are only trying to detect one particular gas.
This flammable gas and smoke sensor detects the concentrations of combustible gas in the air and ouputs its reading as an analog voltage. The sensor can measure concentrations of flammable gas of 300 to 10,000 sensor can operate at temperatures from 20 to 50°C and consumes less than 150 mA at 5 V. Please read the MQ2 datasheet (184k ...
