Build Smoke Detector with Raspberry Pi | High Voltage Code

· The main component we'll be using here besides Raspberry Pi itself is MQ2 Gas Sensor Module. This gas sensor is perfect for measuring LPG, Smoke, Alcohol, Propane, Hydrogen, Methane and Carbon Monoxide concentrations in the air. These concentrations are represented as Parts-per-million (abbreviated ppm). In our case, we'll be detecting particles commonly found in smoke, but you …
