Digi-Key stocking compact power measurement tool for IoT applications

By eeNews Europe

Otii provides simplifies power measurement of devices, especially those targeting IoT applications which demand optimised, long battery life. The Otii solution integrates the measurement capabilities of several test and measurement hardware tools into the Otii Arc, a device that makes it easier for developers to pinpoint which sections of code, associated peripherals, and hardware contribute most to power consumption. Powered by a PC’s USB port or an external 7.0 – 9.0 V power supply, the Otii Arc provides power to the target application whilst measuring and displaying power consumption from below 1 µA up to 5 A without the need to manually change the settings.

The Otii Arc and the accompanying Otii software, can also monitor additional analogue and digital signals, allowing application subsystems to be monitored in parallel to the main power input. Any serial data, from 9600 bps to 4 Mbps, output by the target can also be synchronously captured and time-stamped.

Qoitech’s free Otii Standard licensed software allows the quick review of power consumption from their development PC and shares and compares the results easily. The additional purchase of an Otii Premium License allows developers to access the battery profiling, simulation and scripting capabilities of the Otii software. Using Lua scripting, the Otii Arc can be used to profile batteries, allowing different batches of the same cell to be compared, or to evaluate their performance under environmental conditions that more closely match that of the application. The Lua scripting also enables automated testing.
