MQ2 gas sensor can be used to detect the presence of LPG, Propane and Hydrogen, also could be used to detect Methane and other combustible steam, it is with low cost and suitable for different application. Sensor is sensitive to flammable gas and smoke. Smoke sensor is given 5 volt to power it.
What is MQ2 Gas Sensor? MQ2 is one of the commonly used gas sensors in MQ sensor series. It is a Metal Oxide Semiconductor (MOS) type Gas Sensor also known as Chemiresistors as the detection is based upon change of resistance of the sensing material when the Gas comes in contact with the material. Using a simple voltage divider network, concentrations of gas can be detected. MQ2 Gas sensor ...
A gas sensor is a device that detects the presence of one or more types of gas in the environment. These sensors have wide applications such as security systems of refineries, industrial centers, and even homes. These sensors can detect combustible gas, toxic gas, pollutant gas, and so on. There are several methods for gas detection, the most commonly used is electrochemical sensors. These ...
The Grove - Gas Sensor(MQ2) module is useful for gas leakage detection (home and industry). It is suitable for detecting H2, LPG, CH4, CO, Alcohol, Smoke or Propane. Due to its high sensitivity and fast response time, measurement can be taken as soon as possible. The sensitivity of the sensor can be adjusted by potentiometer. Note. The sensor value only reflects the approximated trend of gas ...
MQ-2 gas sensor has high sensitity to LPG, Propane and Hydrogen, also could be used to Methane and other combustible steam, it is with low cost and suitable for different application. Character Configuration *Good sensitivity to Combustible gas in wide range High sensitivity to …
Sensitive material of MQ-2 gas sensor is SnO2, which with lower conductivity in clean air. When the target flammable gas exist, the sensor’s conductivity gets higher along with the gas concentration rising. Users can convert the change of conductivity to correspond output signal …
There are LPG cylinders which are used as a fuel source for the gas stove. Many a times, disastrous accidents take place due to leakage of these cylinders, in these situations we must administer proper care and safety. Keeping this in mind, in today’s post I have worked on MQ-2 gas sensor (FC-22) powered and interfaced with Arduino Uno.

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 Gas ...

MQ2 gas sensor is also known as chemiresistor. It contains a sensing material whose resistance changes when it comes in contact with the gas.
The Gas Sensor is a sensor which detects gas and smoke with concentration between 300ppm and 10000ppm. He can detect butane, propane, methane, alcohol, hydrogen and smoke. He can be only used Inside, at ambient temperature. He has 2 pins for the power, 1 …
How to configure any MQ sensor and read it out with the Pi will be shown on the example of the Raspberry Pi gas sensor MQ2 in this tutorial. All other sensors (MQ3, MQ-135, etc.) can also be adapted with a few additional steps. Accessories. All MQ-X sensors return analogue signals, which we can not easily read at the Raspberry Pi. One possibility would be to use an Arduino, but we can also use ...
The MQ series of gas sensors use a small heater inside with an electro-chemical sensor. They are sensitive for a range of gasses and are used indoors at room temperature. The output is an analog signal and can be read with an analog input of the Arduino. The MQ-2 Gas Sensor module is useful for gas leakage detecting in home and industry. It can ...
An MQ-2 gas sensor module that outputs an analog value when sensing combustible gas. The higher concentration of the gas is, the greater value it will output. When the value exceeds the threshold set, the signal indicator will light up. High sensitivity to liquefied gas, natural gas, town gas, smog, etc. With a comparator LM393 to output both digital and analog signals at the same time ...
2016-05-05· Está no post na secção “Code” e podia copiar a partir de lá . Reply. Joachim Z. July 1, 2016 at 7:14 am The description of the MQ-2 sensor above includes the sentence “The smoke sensor has a built-in potentiometer that allows you to adjust the sensor sensitivity according to how accurate you want to detect gas.” Please note, that this poti has only an influence on the threshhold of ...
