How to put ESP32 in Deep Sleep Mode?

ESP32 can be configured at five different power modes. Each mode has different power consumption ratings. The different power modes of ESP32 are:
Active Mode
Modem Sleep Mode
Light sleep Mode
Deep sleep Mode
Hibernation Mode

ESP8266 is very popular for building IoT based Projects, but nowadays ESP32 is getting a lot of attention because of its BLE compatibility feature at a lowered cost. It also comes with 32 GPIO pins with a 32-bit dual-core CPU. Although, it offers a lot of features, but it seems to be power-hungry at a normal mode of use. When the applications are powered by the mains supply, there is no matter of hurry, but when they are powered by a battery, and then we must be very conscious regarding the ESP32 power consumption.

ESP32 offers different sleep modes, using which we can save a lot of power and can be able to run our IoT applications for a longer time using the battery source. In this article, we will discuss different sleep modes of ESP32 and will check the current consumption in normal as well as in deep sleep mode. To learn more about ESP32, check the various ESP32 based projects.
