New Development Tool For IoT Energy Optimization


Many Internet of Things (IoT) applications often need an ability to analyze and optimize on how much energy they use. For example, developers may be able to decrease the size and weight of the battery in many high-volume IoT deployments, which could reduce product costs.

Optimize Your System’s Battery Life Using Otii Arc

A new energy monitor and optimizer — the Otii Arc from Swedish test equipment developer Qoitech — simplifies power measurement of devices and gives customers an easy way to see what drains the battery in their products. The Otii power measurement tool is now in distribution from Digi-Key Electronics.

The Otti 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.

Key features of the solution at a glance: 

  • Easy-to-use desktop application for Ubuntu, Windows, and macOS
  • Quick install, plug-and-play setup; start measuring in less than a minute
  • Compact, portable, and quiet; does not require lab environment so can be used anywhere
  • Designed to be used by any developer throughout the stack
  • Continuous system level current and voltage measurements
  • Current auto-range for 0.5 µA to 5 A, with sample rate of up to 4 ksps
  • Subsystem current and voltage measurements via ADC in the expansion port
  • Power supply with output voltage range of 0.5 V to 3.75 V when USB powered, up to 5.0 V when powered with optional DC adapter
  • Measurements continuously synchronized with debug logs from the device under test, collected via UART in the expansion port
  • Recordings can be synced with external debug logs in post processing
  • Real-time analysis; scroll, zoom, and select parts of the current consumption and debug logs while measuring
  • Record and compare multiple recordings
  • Share the recordings for additional measurement or view
