摘要

In this study, STC12C5204AD MCU is used to sample and display the leakage current and the food temperature system output power. The power supply is also able to fulfill the leakage protection by cutting off the output power according to the amount of leakage current intelligently. ADC Linear regulated voltage power supply is designed to use C511 high powered PNP power adjustment tube, a voltage regulator module TL431 and other components which makes it have LDO function and is capable of accepting a wide range of voltage input, as well as high stable 5 V output voltage. Hall sensor is used to detect the current of electric leakage.
