This radio-astronomical pipeline filters, corrects, and correlates the signals from 960 receivers. The figure shows the instantaneous power consumption of three different devices. The correlation between energy use and executed kernels is clearly visible. The shaded area below the curve corresponds to the total energy used by a kernel.

## Installing the PowerSensor
Before starting, turn off and unplug the power of the host system. An Arduino Uno (or similar clone) is at the heart of the PowerSensor. The microcontroller on this board collects the sensor values, interprets them, and communicates them to the host via USB. An optional LCD shield (with 16x2 display) shows the instantaneous power consumption of the (PCIe) device to be measured.
