This water proof, chemical resistant, low drift Humidity and Temperature module from IST :provides a fully calibrated and compensated humidity and temperature digital signal output.

The Digital output is for a I2C interface in a 14 bit resolution. Accuracy at 23 °C is +/- 1.8 % RH  in the span of 0 % RH to 80 % RH. This reading comes with a Response time of less than 4 seconds.

They also have a LabKit with USB Interface to evaluate and implement in your system.

"The Labkit was developed as a Plug&Play tool for a  fast evaluation of the HYGROCHIP digital humidity  sensors. The ready-to-use system consists of a  PC-adapter with an USB connecting wire, a connection adapter with plugs for all product variants."
