Kelvyn reads the outside temperature from a tiny portable sensor Kelvyn displays the current outside temperature from a wearable microcontroller project that you build. It keeps track of the current temperature in either Fahrenheit or Celsius and displays it on an easy to see analog style graphic. It also keeps track of previous timed reading and graphs it over days, weeks and months. It provides averages and trends. It connects easily with Bluetooth and now provides you with up to the second temperature awareness.
