Microcontrollers are the backbone of countless battery-powered devices, and maximizing their energy efficiency is crucial for long-term operation. In this tutorial, we use a thermal camera to visualize how microcontrollers behave thermally as they transition between deep sleep an…

Glad I found this! It’s helpful for my current project. I’m building a battery-powered sensor node that spends most of its time in deep sleep, so I’m trying to get a handle on how temperature and active/sleep cycling affect power draw.

That’s great. Happy to hear! Since you are doing a battery powered application, you might be doing an energy budget calculation. You might be interested in another blog we wrote recently for which we measured the current draw of a similar BMP280 sensor module. We also wrote a cus…

Nice work, this tutorial’s super useful for understanding thermal behavior in sleep cycles. I’ve been testing something similar for a small autonomous rover — it also spends most of its time in deep sleep to save power. For distance sensing, I paired mine with a HY-SRF05 ultraso…
