ESP32 is capable of light sleep, but the wake up source can radically change the power consumption, so to compare with light sleep (see the other video about light sleep) now we test the sleep with external wake up.

But not all esp32 is equal some microcontroller have better battery performance, here we compare DOIT DEV KIT v1, WeMos LOLIN32 and TTGO T8.

This is the fifth video accompanying the tutorial on how to manage, in a practical way, the energy saving of our ESP32.
