Boris Landoni from Open Electronics writes about a new open source Rain Sensor and controller:
Designed to be coupled to an irrigation controller, a weather station or motorized curtains and rolling shutters, it shuts down a relay when rain is detected.

I would like to challenge fellow readers: I’ve read plenty of rain sensor projects articles etc, and I cannot remember a single one providing actual usage data. For example, how does the module behave during X times the sky rained? Can the writer design a sensor to connect to the board that senses light rain or drizzle? How long before the sensor triggers after it starts to rain. Etc.
No data folks. Not a single article or blog post have actual usage data. No data.
So, have anyone seen an article saying such-and-such made a rain sensor and used it and provided some behaviour data? Any data at all…
