PIC 18F45450 LCD Air Conditioner Monitor with USB.

by Jody Wisman

for the Olimex sponsored PCB contest

This is the same as the former Air Conditioner Monitor, but this is working with USB PIC18F45450......

The Pic code generated a virtuel Com port (on mine machine COM6) and so the PC code is the same as the other Air Conditioner monitor

This project read's three DS600 temperature sensors from Maxim/Dallas and two pressure sensors and display's it on a POWERTIP 2 lines by 20 character LCD. I used it to check the airco from a car now I can read the pressure in the system and the temperature inside the car and in the system.....
