Joulescope

Joulescope™ makes the invisible visible, quickly and easily. It enables designers, engineers, and makers to quickly and easily optimize the energy consumption and battery life of a target device.

Instantaneous Values

Joulescope measures and visualizes real-time current, voltage, power, energy, and charge—just like a multimeter, but with greater precision and insight.

Waveforms Over Time

Visualize changes over time, just like an oscilloscope. Easily navigate your data, highlight key regions, and pinpoint where your device consumes the most current and power.

All on Your Computer

Joulescope connects via USB, eliminating the need for external power adapters. Its software is free and open source, allowing you to seamlessly explore your data using a mouse and keyboard.
