As sailing is hobby of me, I wanted to get an idea of windspeed. So I bought an anemometer. As it arrived it seems to have a CANBUS interface. That was new to me, but at the end I managed to connect it to a ESP32 development board.
- Anemometer 3001-FS-RS (CANBUS or RS485)
- MH-ET LIVE Devkit ESP32
- Elecrow UART TTL to RS485 Two-way Converter
- 12V to 5V step-down power converter
Position of the anemometer
The software on the ESP32 (Arduino code) sends every 10 minutes the average windspeed to a local service (API). I still have to make a dashboard to show the results.
