Hi guys... I've designed a low cost humidity sensor based on previous suggestions using a carbon resistor with its coating removed. Here's the schematic I want to build:

Has anybody done this before? Do I need to introduce other stabilizing parts like temperature compensation, etc.? The output it not very linear, so I plan to calibrate it using programming to linearize its output.
