| Abstract: | The intelligent temperature controlling system based on I^2C Bus interface is composed of singlechip AT89C2051, temperature sensor LM76 and software,I^2C bus was simulated by AT89C2051 through I/O interface, and temperature sensor LM76 was controlled by AT89C2051. And universal subprogram was simulated by monitor routine and I^2C bus to realize control function and digital smooth filtering. The system has RS-485 communication interface, and is up to the standard of ACPI. |
