Building an InfluxDB IoT Edge Data Collection Device (Part 2)

The Software

In this installment, I’ll go through the software that I built in the same order as the hardware, just for consistency’s sake. Feel free to jump around to the parts that interest you the most!

The WiFi Sensor

Programming the Particle Photons is super easy using their web-based development environment. They have a desktop version too, based on Atom, but I had regular problems with it so I stuck to the online one. One of the few drawbacks to Particle is that they expect everything to go through their cloud, but their cloud has no way of storing and analyzing data. A rather large weakness, if you ask me. But, even if it didn’t, I’d have had to do things this way because, as stated earlier, I didn’t want to do a cloud-first architecture. I wanted the edge device to collect the data. I wanted to connect to a private Wi-Fi network (served up by the edge device itself) and send all my data there.
