Home Weather Station with Arduino and Raspberry PI

Home Weather Station built with Arduino Pro Mini and Raspberry PI (3 A+)

Note: This repo contains 'release' code and schematics - September 2021 (v3.5)

Dependencies

• OBH Nordica eHome wind meter system 4931 (or similar set of sensor)
• Arduino Pro Mini 328 3.3V/8MHz
• Raspberry Pi 3 A+ and the 7″ touchscreen monitor
• The forked & modified RadioHead library with support of RFM22B and RFM69HCW based radio modules for Raspberry Pi.
• The original RadioHead Packet Radio library for embedded microprocessors maintained by Mike McCauley.
• The original BCM2835 library for Raspbery Pi maintained by Mike McCauley.
• Arduino libraries for communication with the Barometric Pressure Sensor Breakout - BMP180 and Humidity and Temperature Sensor Breakout - SHT15
• Python module for POSIX IPC Semaphores, Shared Memory and Message Queues
• Pyhton library Kivy

GUI (v1.0)

• The main screen - updated every 45 seconds

• The trace sscreen - for last 15 minutes

Structure (v1.0)

arduino

• WStation: code
  • sensrfm: client code for collecting weather sensor data and sending it via RFM69HCW or RFM22B radio
  • other folders: test code for sensors and radio

raspi

• KiCad: KiCad circuit diagrams
• kivy: Kivy GUI code (client_mq.py, display.py and screens.kv)
• rfm: C code for reading the weather data transmissions via the RFM69HCW or RFM22B radio and sending them via POSIX MessageQueue to the Kivy GUI (server_mq.cpp)
