Everything works
For I2C Soil moisture sensor
One year or so with (non-rugged) sensors. They just work. Nothing was broken or broke over that time.
The coating of non-rugged sensors does indeed flake off (in my case it was ~6 months, YMMV), just as description says.
i2c is not an ideal protocol for long-ish wires. Errors do occur, but they are easy to handle in software (sanity checks, median filter and reboot after too many failures gave me months and months of continuous samples from multiple sensors) and hey, i2c version is cheaper! ^^
Couple of suggestions:
- please add a note that sensor address is saved so "smart" people like me won't start making a complex one-by-one startup and address change for a bunch of sensors connected to one SoC :D
- how about configurable attenuation (if the hardware allows)? All the samples I get are well within [300, 600] range, which is a bit of a waste of 16bit precision.
TL/DR: great sensor, nice price, fast shipping

Hi Vladimir, thanks for the review! I will address your suggestions in the documentation asap. Frankly I don't see a point in artificially mapping the result into a single byte - a lot of people with scientific background love the sensor because it gives the most raw unprocessed data - I don't want to lose that.
