This paper is more comprehensive systematically describes the MCS-51 microcontroller to control the core temperature and security functions.
And the driver chip, transistor, assembly language programming, input \ output technology and application of the principle.
In the thermostat system, the multi-point temperature is collecting, Different locations through the temperature corresponding digital temperature sensors were collected transmitted to the control center --MCU
After MCU right to transmit all the values of temperature and the temperature we set up for comparison to the corresponding motor control work. We want to be in the temperature value through our manual to achieve, and that is through the implementation of key changes in the function.
In the anti-theft system, using the infrared, Through infrared radiation to the transistor to control its on - or not achieved, So as to control the core -- MCUto generate interrupt, implementation alarm function.
