Weather station with ESP32 and LoRa
MCU Board - Heltec WiFi LoRa 32 v3 (ESP32 with LoRa and 0.96" OLED Display)
- I'm using two of them to send and receive over LoRa. This is to provide indoor/remote display functions.
Wind Speed, Wind Direction, and Rain Gauge kit - Available from Argent Data or SparkFun.
HiLetGo BME280 breakout board - measures temperature, humidity, and pressure. Not to be confused with the BMP280.
DFRobot MPPT 6V Solar Panel Controller - charges a LiPo battery with the help of the sun
Ambient Weather Solar Shield/Stevenson Screen - I didn't want to 3D print anything major for this project, so I found this on Amazon.
5V 1W Solar Panel
3.7V 1000mah LiPo battery
RJ11 Jack Breakouts - The wind and rain sensor kit uses RJ11 connectors.
Generic LCD2004A LCD module with I2C - for the indoor display.
Arduino IDE
Heltec custom ESP32 library with support for the onboard OLED display and LoRa module
Note: As of March 2023, the Heltec Library has issues with the WiFi LoRa 32 v3 board (ESP32-S3). See this issue for the fix.
Don't install https://github.com/HelTecAutomation/Heltec_ESP32! As of March 2023, it provides conflicting header files with v0.0.7 of the Aaron Lee library.
