Creating a Simple Arduino Fire Detector

arduino fire detector

A fire or flame sensor is simply an infrared LED with an amplifier circuit. Flame radiates infrared signal, which triggers the LED to produce current. This current is converted to voltage for an analog to digital converter to read. Let's see how we can build an arduino fire detector using …
