How to Build a MQ-2 Smoke Sensor Circuit with a Raspberry Pi

This will cover the pinout of the MCP3002 chip as well as all the connections to the Raspberry Pi board. Through these connections, the Raspberry Pi can read the analog voltage output from the sensor. We will make it in our code that if the smoke sensor voltage exceeds a certain threshold, which we will specify, we will make it so that our program outputs the statement, "Smoke detected." Now that we have …
