Most people can tell you the various uses of the umbrella — it keeps the rain off, pokes sleeping train passengers awake, and can be used as an improvised defensive weapon when tension in the hot dog line reaches boiling point. A true Englishman would never deign to employ their brolly so imprudently, of course, but they might just give it an upgrade by packing in a full weather station.
The build uses the Particle Photon as the brains of the operation, interfacing it with several sensors. There’s a DHT11 to handle temperature and humidity measurement, an Adafruit barometric pressure sensor, along with a custom-built anemometer using a brushed motor with 3D printed wind cups. Finally, a breadboard is turned into a rain detector, based on the same principles as those used in automotive applications.
The Particle Photon uses WiFi to tether to a smartphone, deliver the collected data to the cloud via Adafruit IO. This enables the data to be collated and processed further on a PC. Yes, it’s 2018, and they have the internet on umbrellas now.
As we reach further into the depths of winter, it’s one project that could very much come in handy, and [The Gentlemen Maker] has been kind enough to share the code on Particle.io. If that’s not good enough, perhaps you could use your umbrella as a WiFi antenna. Video after the break.
