Rainfall Tip Gauge

1 tip = .011”/.2794mm of accumulation.

I2C addresses of sensors I have

These are my sensors and they work with the addresses in the Arduino code. I strongly recommend running a port scan to make sure your devices are responding in the same manner. Driver.begin() functions can usually be modified for alternate addresses from different vendors.

Extended reliability for rainfall collection. Not as interesting now that we fail WiFi connect more gracefully in v1.3.1 (without tripping WDT)
