The MQ2 Smoke Sensor is a very popular module for detecting smoke and to flammable gases like LPG, Butane, Propane, Methane, Alcohol, and hydrogen. It outputs different voltage accordingly to the smoke/gas level that exists in the atmosphere. The sensor outputs a voltage that is proportional to the concentration of smoke/gas. In other words, the greater the gas concentration, the greater the ...

20160505· The MQ2 gas smoke sensor is an analog sensor. It outputs a voltage between 0 and 5V accordingly to the gas concentration in the atmosphere. The greater the gas concentration, the greater the output voltage. The lower the gas concentration, the lower the output voltage. When the Arduino reads analog values, it returns 1023 when it reads 5V, and ...

The MQ2 Gas Sensor module is useful for gas leakage detecting in home and can detect LPG, ibutane, propane, methane ,alcohol, hydrogen and module have a builtin variable resistor to adjust the sensitivity of the sensor.. Package Include ": 1 x MQ2 Gas Sensor Module "Smoke , Butane Propane Detection"

20160506· The MQ2 smoke sensor is sensitive to smoke and to the following flammable gases: LPG. Butane. Propane. Methane. Alcohol. Hydrogen. 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 ...

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 sensitive material of MQ2 Gas sensor is SnO2, which has lower conductivity in clean air. When the target gas exist, the sensor’s conductivity is higher along with the gas concentration rising. MQ2 sensor could be used ...

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 works on 5V DC …

20211124· The MQ2 type smoke sensor is made of a tin dioxide semiconductor gas sensing material. When it works at a temperature of 200 to 300 °C, the tin dioxide adsorbs the oxygen in the air, which reduces the density of electrons on the semiconductor and thus increasing the resistance. When it comes into contact with smoke, if the barriers at grain boundaries are changed by the smoke, the ...
