Temperature sensor using TMP102
TMP102 is a temperature sensing module from sparkfun. It gives accurate results over other temperature sensors. It uses I2C bus so that you connect some other I2C devices with Arduino.
The given project measures ambient temperature and displays values in degree Centigrade and Fahrenheit. TMP102 is simple and accurate digital sensor which can detect very small changes in temperature (0.0625° C) and is accurate up to 0.5°C. You can get all the details of this project on BUILDCIRCUIT.COM
