MQ2 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 ...
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.
The MQ2 measures a gas concentration of 100 to 10000ppm and is ideal for detecting a gas leak, as a gas alarm or for other robotics and microcontroller projects. The MQ …
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.
· Uma vez que o sensor de gás MQ2 não é compatível com a placa de ensaio, recomendamos esta pequena placa de base útil. É muito fácil de usar e vem com duas saídas diferentes. Ele não apenas fornece uma indicação binária da presença de gases combustíveis, mas também uma representação analógica de sua concentração no ar.
