This is a LoraWan sensor I created partly to test out LoraWan technology for the first time at home. I wanted something flexible that I could install inside another building and trust to report back to the antenna mounted outside my house. Not far however, and essentially only has to pass through one wall.
This sensor measures temperature, humidity, pressure and has an air quality index score which it uses its 4th sensor to determine. It has setup via captive portal wifi. The button on the side can be used to factory reset the device (long press) or toggle the screen on/off (short press).
The source, firmware and information on flashing can be found here.
This is a solder free design that can be built solely by sourcing the right parts from Seeed Studio, although it does use M2 heat set inserts, like a lot of my other designs. Fitting it all in is a little tricky, but it works.
