Tiny Cooling Fan system core components

"Tiny Cooling Fan" system AT89C51 microcontroller as the core components, SCM system to complete the ambient temperature signal acquisition, processing and display functions; draw circuit schematics and PCB printed circuit board diagram with Protel software, visit really made Protues software testing using MCS51 assembly language, the main features of the system is to run the program:
1) "Tiny Cooling Fan" applicability, users only need to set the interface parameters and start the system to normal operation can meet the different users of the most suitable temperature requirements, to achieve the optimum temperature for the real-time monitoring.
2) "Tiny Cooling Fan" system low cost, operation is very simple, you can always write new features add to the software. Scalable interface, just a little change, you can add other key functionality.
