What is the maximum distance for communication between blutooth module and mobile phone? Should they be very close or is there any limitation in the distance!?

I tried this project but i had some problems. What is "i" actually in int i=0 I am using Arduino mega 2560. Is that okay or else i need to change anything. I am using LM 235 instead of LM 35. Temperature that my phone is showing is about 350 deg C. What should i do to get it right? Thanks

yes " i " is variable here. int i=0; You can use LM 235 instead of LM 35. It work very fine. ok not worry bro. 5 volt supply to LM 235 / LM 35 sensor ok, not 9 volt supply because Aref voltage is 5 volt by defalut to arduino ADC conversion. 5 volt supply is only.

Could it monitor more than one temperature sensor at the same time?
