I'm a PICAxe and electronics newbie. I've managed to put together a few circuits including one that reads temperature from a DS18B20 sensor. I'd now like to create a project that can read relative humidity inside my house. I've done some searching and found some relatively cheap parts (looking for under or around $10US), but the circuits required are somewhat complex. Is there an easy to use humidity sensor similar to the DS18B20? I'd also like to have it run at 5V if possible. Any help is greatly appreciated.
