thanks again everybody. god i luv the internet. Just a random unreleated topic. I have a thousand ideas and will have 1 arduino. How many boards do you guys have and do you just build them yourselves? I saw a cheapduino on the instructables site that costs 10 bucks each i think. Is that as cheap as it goes?

thanks for all the responses. I probably will go with one of the Sensirion sensors. Every post I have read has said they are rock solid. That is a good idea to also get some other cheaper sensors and calibrate them with the Sensirion. As for flyboy, how much do you want for 1 or more. Or just let me know when you put them on ebay. I want to play around with one for orchid growing.  
thanks

thanks for the tip on never comparing readings. I have 2 humidity sensors that I was using in another project and comparing the readings drove me nuts. Where would be the best spot to get or look for humidity sensors. I go to digikey and search for humidity and get 20 pages of results. I am just looking to buy 1 for now but if it works out I'll buy a bunch. Any tips on the best source for sensors?
thanks

hello this is my 1st post but very doubtfully will be my last. I am looking for a low cost humidity sensor. It seems that the sht15 is a popular choice for the arduino, but 35-45 bucks each is a bit much. I have also come across the hope rf HH10D for 10 bucks, HUMTEMPSENS for 10 bucks , UPSI G-US.12 for 6.95, and the Humirel HS1101. I make beer wine cheese and am getting into growing indoors. I already can think of a multitude of uses for temp and humidity sensors but dont know where to start. If anybody has any recommendations for a cheap but somewhat accurate sensor please pass that info along. I read in some other site about a guy using the HUMTEMPSENS with an arduino. He said that it uses the same interface as the sht15. So does that mean it uses the same library? I am a newbie to the world of physical computing and my 1st arduino was shipped from adafruit yesterday. Well thanks for reading and I hope that we can find a solution to this issue. It seems I am not the only 1 looking for this solution.
thanks
