A kind of low-cost and high-precision power measuring device is designed, which is realized by hardware circuit and embedded software. The signal acquisition circuit, switching value input and output circuit, communication circuit of the device are analyzed. The power calculation program, storage program, timer interrupt program and communication program are described. The device has been applied in the field, and the application shows that the device meets the requirements of industrial level and has the merits of low cost, high precision and high stability.
