We’ve featured a lot of Arduino projects focused on the indoors and home automation in the past, with outdoor builds being more difficult to come by.

When we do find them they’re usually worth your time, as is the case with this Forest Fire Detector by Sigfox software engineer Louis Moreau.

The core of the project is an Arduino MKRFOX1200 hooked up to an array of sensors and a 1200mAh battery. Those sensors include a Waveform flame sensor module, a DHT11 temperature & humidity sensor, and an IR receiver.

You can see the prototype in use below, picking up the flame from a regular lighter. When the LED lights up the fire has been detected.

The project is connected using Sigfox to send out messages if a fire breaks out, and it’s all wrapped inside of a wooden birdhouse. You could always make your own, but the version you see here is a €10 unit from Amazon.

Moreau suggests expanding the idea with solar panels to keep things going for longer. We’d also suggest a better enclosure to protect the electronics from the weather.

You can find a full guide to replicate this project over on the Arduino Project Hub. You can also watch the video below for a timelapse of the soldering process and a quick assembly demo.
