Feb 01, 2021· The gas sensor module consists of a steel exoskeleton under which a sensor component is placed. This sensitive element is subject to the current through the sensor wire. This current is known as the heating current through which the gases ionize the sensitive material and are absorbed by the sensitive material.
The sensor is calibrated prior to shipping. If you do choose to calibrate, a one‑point calibration at atmospheric pressure is adequate for most applications. To perform a onepoint calibration. Connect the Gas Pressure Sensor to an interface following the steps in the Getting Started section of this user manual.
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.

May 05, 2016· 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 ...
Circuit design Gassensor created by AirtonB with Tinkercad
Place sensors close to the possible gas/leak source. Place sensors in areas where air currents are likely to produce the highest gas concentration, including areas where gas buildup is likely, such as corners or stopping points of gasreleasing moving devices. Factor in the monitored gas’s vapor density when compared to air.
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.
