In the thermostat system, themulti-point temperature is collecting, Different locations through the temperature corresponding digital temperature sensors were collected transmitted to the control center --MCUAfter MCU right to transmit all the values of temperature and thetemperature 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 dradiation to the transistor to control its on - or not achieved, So as to control the core – MCU to generate interrupt, implementation alarm function.
