The PowerSensor hardware consists of an Arduino microcontroller board, current sensors (ACS712), a PCIe riser card (to measure the power drawn from the motherboard), an optional LCD screen, and a USB cable that connects to the host. In this typical scenario, we use three sensors that measure the PCIe slot power (12 V and 3.3 V) and the external PCIe cable power. The microcontroller interprets the readings from the current sensors, and reports the measured power consumption via USB to the host.
