DHT11? Code/Schematics?

yea that one is a analog, and it should work, but its got a +/- of 5%RH which I was hoping to get a bit more acurate than that. I found a Humidity sensor that requires a 555 timer circuit and it outputs frequency based on RH value and its got a +/- of 1%, its a HS1101, its also only $4 on ebay. I have found out though that the sensor itself is only a varible capacitor based on humidity levels, this one ranges from 163pf @ 0% humidity to 201pf @100%. and I was wondering if its possible to use the RCTIME with a fixed resistance to read the pf values, although that is very small, also I would like to have a resolution of 100. now I can build the 555 circuit and use PULSEIN but it would be cool to be able to read the humidity with only a sensor and a resistor.

here is the datasheet on the sensor, it also has the info on the 555 in it. it says with the 555 circuit it can output 5k-100khz pulse but only uses a small range in those limits, so if I do use the 555 I will set it to run from say 20k-30k based on RH values if PULSEIN can handle that.
