Does anyone have any information on connecting the newer RG-15 Rain Gauge to ESP32? Thanks……
At the moment, we don’t have any tutorials about that.
Can you share a link to the rain gauge that you have? That can be something interesting to explore.
It should be relatively simple to modify the example in their blog. The example uses ethernet for web server so you would replace all of that with the ESP32 WiFi and ESPAsyncWebServer. The ESP32 dev kit boards have two 3.3V TTL serial ports (GPIO 1 & 3 and GPIO 17 & 16) so you should be good to go connecting the RG-15 rain gauge. Note that this should work fine for development/testing but you would need full RS232 for any distance cabling.
