The Qoitech Otii Arc power analyser from Qoitech is an amazing tool for the development of IoT projects. This power analyser, DC power supply, and data logger in one package, provides accurate measurements of current and voltage, to optimize power consumption effectively.
Furthermore, the Otii Arc can be powered via USB or an external DC adapter. The device will act both as a 5V power supply and a measuring unit at the same time. It provides a high-resolution measurement range from microamps to amps, with a sample rate of up to 4k samples per second.
Finally, the Otii Arc features an intuitive software package, enabling seamless data analysis and project management. The software allows users to view real-time measurements and generate statistical analyses based on the measurements. Furthermore, the software allows you to share data with others.
This is the predecessor of the Pro version. The features/hardware are the same, as you can read
here. We offer it for a special price. There is no disadvantage compared to the newer (more expensive) Pro version.
