Overview
WeatherStation is an open-source printed circuit board by steand, from the steand/WeatherStation repository on GitHub, published under the GPL-3.0 licence. It is a 4-layer board of 88.9 × 68.6 mm with 23 parts on 53 nets, routed with 162 tracks and 24 vias.
It is built around the ESP-WROOM-32D and IRLML2244. Its parts include 7 connectors, 5 ICs, 4 capacitors, 4 resistors and 2 switches. It belongs with the home automation and IoT boards and the ESP32 boards of this library.

Version 0.1 (under construction, not stabil)
In diesem Projekt habe ich mir eine kleine Wetterstation gebaut. Meine Motivation war, dass es eigentlich nichts erschwingliches gibt was in die offenen Smart-Home (bei mir openHAB2) integrierbar ist.
Leistungsmerkmale:
- Windgeschwindigkeit
- Windrichtung
- Regenmenge
- Regensensor
- Temperatur
- Luftdruck
- Luftfeuchtigkeit
- Helligkeit
Zur Steuerung meine Markise benötige ich Alarme für Regen und Windgeschwindigkeit. Die Rolladen werden mit Hilfe der Helligkeitssensor gesteuert.
Für Windgeschwindigkeit, -richtung und Regenmenge dienen die Sensoren eine AOK5055. Regensensor ist ein "China Modul". Temperatur, Luftdruck und -feuchte basieren auf einem BME280, Helligkeit auf dem BH1750.
Die Microcontroller Basis ist ESP-WROOM-32u (u wegen der Antenne).
Als Stromversorung dient eine 18500/3000mAh Batterie die über ein Modul(TP4056) geladen wird. Der Lader wird über ein MPPT-Modul (China) von einem 5W/12V Solarpenel versorgt. Als SDK setze ich platformIO auf Basis von Atom ein. Für Schaltpläne und Platinenlayout (Entwicklerplatine) nutze ich KiCad.

Questions
How big is the WeatherStation PCB?
It measures 88.9 × 68.6 mm and has 4 copper layers, 1.6 mm thick.
What parts does the WeatherStation use?
23 parts, built around the ESP-WROOM-32D and IRLML2244. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the WeatherStation KiCad files?
From the steand/WeatherStation repository on GitHub, at the commit this page was made from: the board is doc/kicad/WeatherStation.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the WeatherStation design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
