In this video we will show you the difference of the power mode Deep Sleep and Deeper Deep Slep (Power Down Mode). We will demonstrate this with and ESP-12F and an ESP-01.
We all know that the ESP8266 can Deep Sleep at only 20 microampere. Did you know that you can put it in power down mode at only 2-3 microampere?!
See this forum post for the original idea: www.esp8266.com/viewtopic.php...
When you are running the ESP8266 on batteries it is a very good idea to make the device sleep as much as possible to save power. Deep sleep saves the most power of all the sleep modes. In Deep sleep mode the ESP8266 only consumes about 20uA.
But we are going to make the device hibernate at only about 2-3 uA. That’s only 10% of power consumption of the deep sleep mode. I’m going to show you how to achieve this and also tell you why many makers fail to do it.
This works for ESP-01, ESP-12E, ESP-12F and ESP-12N.
Do not work for ESP-12S and ESP07S. But, you can make it work for the ESP-01S.
The secret pull up resistor is the key!
