Sensitive material of MQ2 gas sensor is SnO 2, which with lower conductivity in clean air. When the target flammable gas exist, the sensor’s conductivity gets higher along with the gas concentration rising. Users can convert the change of conductivity to correspond output signal of gas concentration through a simple circuit. MQ2 gas sensor has high sensitivity to propane and smoke, also can

Detection principle: MQ2 type of smoke sensor adopts stannic oxide as the semiconductor gas sensitive material which is the surface ionic Ntype semiconductor. When the temperature is in the range of 200~300℃, the stannic oxide adsorbs the oxygen in the air to form into negative oxygen ions, so that the electron density of the semiconductor is decreased and its resistance is increased.

6/5/2016· What is an MQ2 Smoke Sensor? 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 detect gas.

Arduino UNO Gas Sensor 5V VCC GND GND NC NC Analog A0 SIG You can gain the present voltage through the SIG pin of sensor. The higher the concentration of the gas, the bigger the output voltage of the SIG pin. Sensitivity can be regulated by rotating the potentiometer. Please note the best preheat time of the sensor is above 24 hours.

The output voltage from the Gas sensor increases when the concentration of gas increases. Sensitivity can be adjusted by varying the potentiometer. Please note that the best preheat time for the sensor is above 24 hours. For detailed information about the MQ5 sensor, please refer to the datasheet provided in Resources section.
