This is a colourful temperature gauge that reads out temperature in Celsius or Fahrenheit (user selectable). The temperature is displayed both in a digital readout and an analog bar graph.
This affordable temperature display includes a temp probe and convenient switching between Celsius and Fahrenheit with the blue button. It quickly hooks up to +5V and GND from an ATX power supply Molex connector. You can always hack in your own +5V and GND by splicing into the red and black wires and soldering them to your own supply such as a USB breakout, SLVR-1, 5 Volt Switching regulator, or just a 5V regulator on it's own. We did a few tests and found that this LCD can operate at voltages as low as 2.7V but the backlight is very dim, if you changed the backlight resistor to a lower value you could probably run this display off a couple 'AAA' batteries or a small LiPo!
