Hello all.
It's a small project that connects to the USB port for serial comm and power and displays the temperature in a windows application.
The circuit uses a 08m chip with a DS18B20 digital 1-wire thermometer. The connection to the usb is done through a USB to TTL cable bought from eBay. The temperature can be displayed either using a simple serial port comm program or by using a small Liberty Basic application I wrote.
Schematics, PCB circuit, source codes are all available here: http://steliosm.net/site/?Projects:USB_Thermometer
