MQ2 GasSensor als anschlussfertiges Modul für Arduino und Raspberry Pi. Einfach zu nutzender Sensor zum Messen der Konzentration von LPG, iButan, Propan, Methan, Alkohol, Wasserstoff und Rauch in der Luft . Der MQ2 misst eine Gaskonzentration von 100 bis 10000ppm und ist ideal zum Erkennen eines Gaslecks, als GasAlarm oder für sonstige Robotik und MicrocontrollerProjekte. Die Sensoren ...
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 ...
· Generally, for gas leakage detection (home and industry), we will use the MQ2 module. It is suitable for detectingH2, LPG, CH4, CO, Alcohol, Smoke, or Propane. Due to the high sensitivity and fast response time of it. But, in this design, we used the MQ2 sensor for the smoke situation. This sensor has four outputs, namely, Vcc, ground, D0, and A0.
Principle: The MQ series of gas sensors use a small heater inside with an electrochemical 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 MQ2 Gas Sensor module is useful for gas leakage detecting in home and industry. It can detect LPG, ibutane, propane, methane ...
· 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 is a metal oxide semiconductor type gas sensor and contains a sensing element, mainly aluminiumoxide based ceramic, coated with Tin dioxide, enclosed in a stainless steel mesh. Concentrations of gas in the gas …

· 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
· The alcohol/Gas sensor we used is that the MQ135 sensor. T his is a sensor that’s not only sensitive to alcohol, particularly ethanol, which is the kind of alcohol that’s found in wine, beer, and liquor. rather than MQ135, you’ll be able to use MQ2, MQ3, MQ5 module also . Basically, all of them have similar functions.
MQ2 Sensor is a gas module and it is suitable to detect Hydrogen, LPG, Smoke, CO, and Alcohol. It has high sensitivity and fast response.

OLIMEX© 2015 MQ GAS AND AIR QUALITY SENSORS AO (Analog Output) pin of SNSMQ2 gets connected to A0 pinhole of the shield connector of OLIMEXINO328 GND (Ground) pin of SNSMQ2 gets connected to GND pinhole of the shield connector of OLIMEXINO328 VCC (Voltage from power supply pin of SNSMQ2 gets connected to 5V pinhole of the
The MQ2_Gas_Sensor module mainly consists of a MQ2 gas sensor which is stable and responsive. The sensor uses SnO2 as its gas sensitive material. When its surrounding environment has combustible gases its conductivity change is positively proportional to the gas concentration and this change will be converted to analog output signals. Its sensitivity can be adjusted via the potentiometer.
· Wie man jegliche MQ Sensoren konfiguriert und ausließt wird am Beispiel des Raspberry Pi Gas Sensor MQ2 in diesem Tutorial gezeigt. Alle anderen Sensoren (MQ3, MQ135, usw.) können mit ein paar zusätzlichen Schritten ebenso angepasst werden. Zubehör
· In this tutorial you are going to learn about Gas Sensor(MQ2) and the interface with Arduino UNO both in Analog and Digital mode. Theory. Mainly we can say it is a Metal Oxide Semiconductor(MOS) type Gas Sensor. It detects gas on change of resistance of the sensing material, when the it comes nearer to sensor.
