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

The reallife diagram of the circuit above is shown below. So to power the smoke sensor, we connect pin 2 of the smoke sensor to the 5V terminal of the raspberry pi and terminal 3 to the GND terminal of the raspberry pi. This gives the smoke sensor the 5 volts it needs to be powered. The output of the sensor goes into the MCP3002 pin CH0, which ...
