Temperature Sensor

I purchased a temperature sensor that connects to the Arduino quite some time ago. I finally got it working by finding the library and the discovery that it’s actually a digital output. I purchased a DS18B20, which is a three wire digital type job. The wires are 5v, 0v and the signal wire.

It’s the little almost shiny thing top right corner of the radiator is the DS18B20
Almost 9ÂșC while i was doing this.

It seems to work, I also have a switch to over ride turning the fan on. I felt this was prudent in case I had set the ‘on’ temperature too high.
