碩士 === 健行科技大學 === 資訊工程系碩士班 === 106 === Recently, IoT(internet of things) becomes one of major subject of information technology.Using WI-FI to connect to internet brings more convenience. However, operating and data transformation in the daily work will consume electric power. Thus, to saving electric power also becomes an important topic. In this research, we use ESP32 MCU as an example. We use Arduino IDE to burn the programs with different power consuming into an ESP32 MCU and use a circuit to measure the voltage of the battery used by the MCU dynamically. By this method, we can observe that difference of power consuming among different programs. In the experiment, we found that the data transformation rate will affect the power consuming significantly. However, for many applications, we need enough data transformation rate to reach the effect. We believe that the power consuming and data transformation rate the trade-off between will become an important subject in the future.
