Hello everyone,

I have HH100D humidity sensor. It outputs a frequency signal, which I know how to handle. However, it also has a small EEPROM with calibration values that is available via I2C. Those values are necessary to get the actual humidity.

The problem is, that I'm very new to I2c. I cannot figure out how to read out those bytes. I've googled for half a day and still got no solution.

There's something I have:

Can anyone please help me?
