What ?

This is a Arduino library for the Silabs Si7005 temperature/humidity sensor. The library makes it easy to use the sensor and all of its features.

Why ?

Because I think it's an interesting sensor, and I wanted to test it. I couldn't find any library or sample code on the internet, so i wrote my own.

Getting started

Copy the directory Si7005 to you Arduino library folder.

Load the Arduino IDE and open the example program from the file menu.

The humidity measurement is dependant on the temperature measurement, and uses the last measured temperature. If no temperature measurement is done at all, a default value of 25.0C is used.
