Build your own binary thermometer with this easy kit! The thermometer is powered by a USB connection to a computer, USB hub, charger or an external 5 volt power supply. Select Celsius or Fahrenheit units with a single pin jumper.

Reading is as easy as simple addition. The left column of lights represents the tens and the right column the ones. The value for each lead, starting at the bottom is 1, 2, 4 and 8. So the temperature in the picture above is 1+2+4=7 for the tens and 1+2+4=7 for the ones, making the reading 77 degrees.

This new version has the temperature sensor thermally isolated. Also the GND and +5V pins are labeled on the USB connector for easy modifications.
