22/12/2020· The MQ2 is one type of gas sensor, which can sense Smoke as well as LPG, Alcohol, and Methane. Arduino board is the main brain of this system that controls the whole system. The MQ2 sensor continuously measures Smoke level in the air and sends data to the Arduino board. Then Arduino prints the Smoke level value on the OLED display in the PPM unit. The LEDs and Buzzer used as …
05/06/2019· The MQ-2 smoke sensor is sensitive to smoke and also responsive to the following flammable gases: LPG. Butane. Propane. Methane. Alcohol. Hydrogen. The resistance of MQ2 varies depending on the type of gas. The smoke sensor has a built-in potentiometer that adjusts the sensitivity of the sensor based on the accuracy of the gas you are testing.
Grove - Gas Sensor(MQ2) 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 ...
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 ...

23/02/2016· Both MQ5 and MQ2 are basically gas sensors but their range of sensing different gas levels vary. For example, MQ5 can sense LPG in a broader range of 200 ppm to 10000 ppm, where as the range of MQ2 for LPG is short and is from 5000 ppm to 10000 ppm. Similarly MQ2 is sensitive to smoke where as MQ5 is not that sensitive to smoke. So we can not choose MQ5 gas sensor to …
04/01/2018· MQ2 Equivalent sensors: MQ-6, AQ-2, MQ-306A, AQ-3 . Selecting between Sensor type and module type. When it comes to measuring or detecting a particular Gas the MQ series Gas sensors are the most commonly used ones. These sensors can either be purchased as a module or as just the sensor …

12/02/2018· Gas Sensor (MQ2) module is useful for gas leakage detection. This is a sensor that detects smoke and to the following flammable gases: LPG Butane Propane Methane Alcohol Hydrogen Due to its high sensitivity and fast response time, measurement can be taken as soon as possible. The resistance of the sensor is different depending on the…
19/11/2020· Le MQ-2 est un capteur qui permet de détecteur du gaz ou de fumée à des concentrations de 300 ppm à 10000 ppm. Après calibration, le MQ-2 peut détecter différents gaz comme le GPL (LPG), l’i-butane, le propane, le méthane, l’alcool, l’hydrogène ainsi que les fumées.
18/02/2021· Using a simple voltage divider network, concentrations of gas can be detected. MQ2 Gas sensor works on 5V DC and draws around 800mW. It can detect LPG, Smoke, Alcohol, Propane, Hydrogen, Methane and Carbon Monoxide concentrations anywhere from 200 to 10000ppm. Here are the complete specifications . Operating voltage: 5V: Load resistance: 20 KΩ: Heater resistance: 33Ω ± …
The MQ2 Gas sensor has a built-in variable resistor that changes its value according to the concentration of gas. If the concentration is High, the resistance decreases, if the concentration is low, the resistance increases. Besides the built-in resistor, it is necessary to include load resistor, Load resistor serve to adjust sensor sensitivity and accuracy, it’s value can range from 2k ohm ...

26/03/2016· MQ-9 gas sensor. MQ-9 gas sensor has high sensitity to Carbon Monoxide, Methane and LPG. The sensor could be used to detect different gases contains CO and combustible gases, it is with low cost and suitable for different application. The sensitivity of the sensor can …
The gas sensor needs about 5 volts of power in order to operate. This is done by connecting 5 volts to Vcc and GND. The Output pin gives out the voltage reading, which is proportional to the amount of smoke that the sensor is exposed to. Again, a high voltage output means the sensor is exposed to a lot of smoke. A low or 0 voltage output means the sensor is exposed to either little or no smoke ...
