Otii use cases

Explore all the set-ups and use cases with Otii products that will bring you closer to the longer battery life of IoT and embedded devices.

Power and current profiling

Measure, analyze and optimize your embedded device’s real current and power consumption. Enjoy the high dynamic range and high-resolution measurements.

Otii products: Arc/Ace

UART logs sync with power measurements

Synchronize your debug logs with power measurements to understand what drains energy. Insights are the first step to optimizing. Iterate measurements for all firmware changes.

Otii products: Arc/Ace

Subsystem measurement/secondary current channel

Examine how each subsystem affects current consumption and voltage levels.

Products needed: Arc/Ace

In-line mode/Ampere meter mode measurements

Measure the current, voltage, power, and energy in line with the power source and your embedded device. This setup is like a multimeter, but it also measures current and voltage simultaneously.

Otii products: Ace

Control device via AT Command while power measuring

Optimize your device’s eDRX and PSM settings by changing them in real-time while measuring. Automate this further with a script. The Python script is available at Qoitech Github.

Products needed: Arc/Ace

To automate also Otii Automation Toolbox.

Automate low power measurements

Automated testing can be set up with Otii Arc/Ace and Otii automation Toolbox, which gives access to the Otii TCP Server API and scripting possibilities.

Products needed: Arc/Ace and Otii Automation Toolbox

Test and validate batteries for IoT and embedded devices

This use case provides an efficient and scalable set-up for incoming battery inspections and benchmarking different batches and brands.

Products needed: Ace and Otii Battery Toolbox

Measuring effects of lithium-based battery passivation

This use case provides a setup for measuring and analyzing the passivation effects of lithium primary batteries under different idle mode durations, temperatures, and state-of-charge conditions.

Products needed: Ace and Otii Battery Toolbox

Setup for evaluating photovoltaic performance with Otii Product Suite

Evaluate photovoltaic performance for embedded electronics

Evaluate photovoltaic system performance for your embedded and IoT devices. This setup provides insights into your application’s PV cell and storage performance.

Products needed: Ace and Otii Battery Toolbox

Regression testing

Multiple current and power measurements in the same graph and project. Compare, analyze, redo. Regression testing made easy.

Products needed: Arc/Ace

Battery life estimation from measured power profile

Get a quick battery life estimate from your measured power profile. Iterate for every new profile. Use battery capacity from datasheet or data from battery profiling.

Products needed: Arc/Ace

Logic analyzer

Connect DUT digital signals to GPIs to monitor logic levels like a logic analyzer. Use the MCU GPIOs as status indicators and view them in the Otii desktop application.

Products needed: Arc/Ace

External shunt resistor/Differential measurement

Measure current and voltage without using the internal power supply of Otii hardware.

Products needed: Arc/Ace

Power source and measure embedded energy consumption

The simplest yet most powerful set-up for continuously monitoring and profiling energy consumption in embedded or IoT devices.

Debug power measurements with UART output logs

Correlate and debug unwanted current peaks and elevated energy consumption in your embedded device with UART output.

Subsystem power measurement of your embedded device

By measuring the power usage of individual subsystems on the DUT, you can better understand how energy flows within the device and identify which components consume the most power.

Ampere meter mode current and power measurements of embedded devices

This set-up enables ampere-meter type of measurements but can be extended to include power and energy as well.

Automate low power measurements

Automated testing can be set up with Otii Arc/Ace and Otii automation Toolbox which gives the access to Otii TCP Server API and scripting possibilities.

Test and validate batteries for IoT and embedded devices

This use case provides an efficient and scalable set-up for incoming battery inspections and benchmarking different batches and brands.

Evaluate photovoltaic performance for embedded electronics
