Sometimes a project doesn’t have to be technically amazing to win over our hearts. [Malte]’s ESP8266-based weather station is so cute, and so nicely executed, that it’s easily worth a look. It could totally be a commercial product, and it’s smaller than a matchbox.
It combines temperature, humidity, and barometric pressure sensors on one side of a PCB, with pads for soldering a pre-built ESP8266 module on the other side. Solder it all together and flash the firmware and you’re almost all set.
The final step is to configure it to work with the network. For this, [Malte] built in a nice web-based configuration (and display) application. It also can log its data to an MQTT system, so there’s a bunch more configuration (which we’re trying to make easier) needed there, and the web frontend makes that light work. Everything, from the hardware to the firmware, and even a pre-compiled binary, is up on his GitHub. Very complete and very well done.
