With the continuous development of chip industry and electronic science and technology, the measuring accuracy of the chip and embedded chip processing speed rapid ascension, this design is to ST's stm32F1 series as the master control chip, HT7038 series chips as a measurement module, measure voltage, current, power, electrical parameters, such as judgment with the usage of electrical appliances, And display the final results on the LCD screen. This design innovatively uses cosine similarity algorithm to improve the identification accuracy of electrical appliances; The innovative method to solve the problem of misjudgment of low-power electrical appliances when high-power electrical appliances are turned on is put forward.
