Lesson 22 Gas Sensor sunfounder

MQ2 gas sensor is a kind of surface ion type and Ntype semiconductors, which uses tin oxide semiconductor gas sensitive material. When ambient temperature is in 200 ~ 300℃, tin oxide will adsorb oxygen in the air and form oxygen anion adsorption to decrease electron density in semiconductor so as to increase its resistance. When in contact with the smoke, if grain boundary barrier is ...

Experiment 3 How to Use MQ2 Gas Sensor sunfounder

Connect pin A0 of the gas sensor to pin A0 of the SunFounder Mega 2560, and D0 to pin 7. The higher the smoke concentration is, the lower the resistance of the gas sensor gets. Thus, the voltage of the gas sensor decreases, which means the voltage of pin A0 increases. If the voltage of A0 is greater than the threshold, LM393 will output low level. Thus, the LED will light up and pin D0 will ...
