Does anyone has any experience in buying temperature and humidity sensors and displays? Is there any reliable source/seller/website that anyone used before? My requirement is that I should be able to sense temperature of room and humidity. If its programmable (I can connect to some computer and get inputs and outputs in some form) then its fine, but basic sensing should work precisely.

what exactly do you want it for ? Just for checking the temp/humidity in your place or do you want to do something with that data too?
