This video introduces Joulescope, a new low-cost energy analyzer, which measures current and voltage, then computes power and energy. The video includes two demos. The first demo is a static measurement. The second demo uses an Arduino Pro Mini to...

Multimeters are a necessary tool for developing electronic devices. In this article, we will explore the challenges of using a multimeter to estimate the energy consumption of an example device: a microcontroller-based wireless sensor. Current measurement is performed using an...
