After the timed, alarm and Serial wake-up, the most used one is the wake-up via an external source. In this case, we must pay attention to the pinout of our device to select the correct pin in the correct situation.
We have already described Idle mode and the relative power consumption, in this article we continue to measure power consumption of other sleep modes to have a brief comparison.
ESP32 has the ability to take advantage of many energy saving modes, but when you set sleep you also lose the status of the pins, but there is a way to preserve it and we will analyze it. Furthermore, the esp32 has powerful features such as the UPL a low-power processor that can wake you up in case of need.
ESP32 has the ability to take advantage of many energy saving modes, but if you use more aggressive sleep you can lost session, we look to how preserve the data and how to wake at a given moment in time and via touch.
ESP32 has the ability to take advantage of many energy saving modes, here we will understand how to put the device in deep sleep and hibernation mode but above all we will try to understand the differences.
