Best Way to Optimize Power Consumption in an Arduino-Based IoT Project

[Jane Will]

Hi everyone,


I’m a student working on an IoT project using Arduino, and I need to optimize power consumption since the device will run on a battery. I’m considering using sleep modes, reducing clock speed, and optimizing code execution, but I’m unsure which approach will have the most impact.


Would a low-power microcontroller like ATmega328P (Arduino Pro Mini 3.3V) be a better choice than a standard Arduino Uno? Also, what are the best libraries or techniques to efficiently manage power in an IoT system?

Any advice would be greatly appreciated!

Thanks!

It all depends on your exact requirements - IF you can, sleep mode is by far the best option, and the Pro MIni is a far better choice than an Arduino Uno, as the Arduino board has too many other items wasting lot's of current.

Personally I use PIC's for such purposes, as they are fairly optimised for low power usage - and I'm usually looking for 5-10 years battery life.

You usually need to be looking at average current consumption below 100uA to get really long life, and special batteries as well (shelf life is often less than 5 years).

Added to sleep you might google "energy harvesting embedded", lots of
hits getting ambient energy.
