Power meter has been industrial instrumentation important, widely used in the field of electrical and electronic technology. At the same time with the development of modern computer technology widely and deeply, SCM in the use and development of increasingly had shown its important status. Microcontroller penetrated into every aspect of our lives, which is almost difficult to find traces of the field without MCU. This paper is mainly based on the single chip microcomputer as the core, with the appropriate external circuitry, by sampling the voltage and current, through the digital analog conversion, the analog signal into digital signal into the microcontroller, through the program, and then through the 1602 LCD display current, voltage to be measured and the power of the original. SCM is the core part of the whole design is the design of the whole circuit, measurement, conversion, display and output can be realized only on current and voltage measurements show, has been measured on electronic devices power. Measurement of this design can be achieved on the device current vo
