PIC based small thermometer with USB interface

Device is more experimental and tend to be used to measure indoor and outdoor temperature. It uses PIC 18F2550 microcontroller with built in USB peripheral. Microcontroller reads sensor (TC1047A ) data and sends it via USB to PC.

USB firmware is taken from Microchip, so not a big knowledge of USB specific software is required. Hex file and other project details are available for download. Author left possibility to connect other sensors (humidity, pressure) to board and syndicate it to the web with Google earth information.
