Otii is a developer tool designed by Qoitech that simplifies measurement and analysis of energy consumption, enabling energy optimization for long battery life of IoT devices and apps. The Otii solution includes a compact and portable measuring unit, the Otii Arc, and an easy-to-use, comprehensive desktop app for Ubuntu, Windows, and macOS. The Otii UI is intuitive and allows for real time analysis, making it easier to see what drains the device’s battery. The Otii Arc acts both as a power supply to the tested IoT device and as a current and voltage measurement unit, allowing for a compact and easy-to-use setup for developers, anywhere in the stack.
THE OTII SOFTWARE runs on multiple platforms, is quick to install and provides means for continuous measurements. The UI is intuitive and allows for real time analysis; scroll, zoom and select parts of the current consumption while measuring. New recordings are easily added on top of the previous ones which makes it easy to track changes in the power consumption throughout development. For iterative tasks, automated testing can be performed by built-in scripting features.
THE OTII ARC acts both as a power supply to the tested IoT device and as a current and voltage measurement unit. It can be powered by USB from a laptop for portable and compact measurement set-ups, or by a 9 V DC power supply. It provides up to 5 V output voltage and current measurements with a sample rate of 4 ksps for the range of 1 µA – 5 A. An additional measurement channel is available via ADC in the expansion port, which also provides UART, Digital I/O and SENSE pins.
