i want to install ,if possible, inexpensive temperature sensors in a root cellar area used for storing food. is there a way to do it wireless?? I was wondering if those cheap radio chip transmitters that retailers use for tracking could be used? anybody ever do anything like this?

Hi...A good temprature sensor is the LM35.... A couple of PIC microcontrolers, a small hybrid transmiter and receiver, and yes it can be done...Daniel.

are there accurate cheap voltage meters that can do mv
accurately,and maybe simple conversion,..I mean little LCD meters about an inch or so that might be used in battery monitoring setups, not a multimeter or anything like that.?

Do you want to measure the actual temperature and display it remotely or would you be content with a single indicator that the temperature was above or below a set value?
