Measurement of energy consumption is an important part of the embedded and IoT system designing. Most of these systems are battery operated or have limited power resources, so to design power efficient systems it is imperative to have some mechanism for power or energy estimation. The paper presents a cloud-based power profiling system for embedded devices. The system determines the current by measuring voltage drop across a shunt resistor which is connected in series with the test node. The power measurement data is uploaded on a cloud server using MQTT protocol. This method provides real-time monitoring of the power consumption of the devices under test. A dashboard is built on the cloud platform for real-time monitoring of power-related information about the test device. The data can also be stored on a local system as well using UART communication.
