How to Build a MQ2 Smoke Sensor Circuit with a Raspberry Pi

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. A low or 0 voltage output means the sensor is exposed to either little or no smoke ...

Gas Sensor Library for Proteus The Engineering Projects

20160502· In this Gas Sensor Library for Proteus, I have added eight different Gas Sensors, which are used for detection of different gases. As we all know that Proteus is a simulating software so it won’t be able to detect the gas in real in Proteus. So, that’s why I have placed a Test Pin in each of these sensors so when you make this pin HIGH, then it means the gas is present and if this Test Pin ...
