Measure power consumption with Otii tool

A usual question you have when designing a device is the autonomy of your battery and the power consumption of your device. By the past I’ve tried different tools for this usage. Starting with USB sticks power consumption, only working for high consuming devices. They are low precision. Going to multimeter tools with USB connectivity precise but sampling at 3-5Hz only. During a certain time I’ve plan to make a solution on my own and finally I’ve found the OTII tool from QOITECH on the recommendation of friends from Sigfox community.

Here is my experience with that tool.

Battery technologies usually used for IoT compared

As it is a recurrent question to find the right battery for an IoT design, I decided to write a post about this topic. I’m not claiming to be an expert of this and I’ll not give insight on this. The purpose is to list the different technology existing with the main characteristics to be able to use the best fitting technologies quickly.

This post is presenting a table of the different battery’s technologies available with the main characteristics. These characteristics are global one regarding the technology. Each of the battery vendor can have specific specifications a bit different. You will need to take a look on datasheets details.
