The ESP32 family includes the chips ESP32-D0WDQ6 (and ESP32-D0WD), ESP32-D2WD, ESP32-S0WD, and the system in package (SiP) ESP32-PICO-D4. At its heart, there's a dual-core or single-core Tensilica Xtensa LX6 microprocessor with a clock rate of up to 240 MHz. ESP32 Deep Sleep In deep sleep mode, the CPU, most of the RAM and all the digital peripherals are powered off. The only parts of the chip that remains powered on are: RTC controller, RTC peripherals (including ULP co-processor), and RTC memories (slow and fast). The chip consumes around 0.15 mA (if ULP co-processor is powered on) to 10µA.
ESP32 has 34 GPIO pins, where only a subset can be used as output, as ADC channel, as DAC channel and as GPIOs in deep-sleep mode, the so-called RTC GPIOs. Some of them are used by special SoC components, e.g., as touch sensors.

③:Deep-Sleep does not require Wi-Fi connection to be maintained. For application with long time lags between data transmission, e.g. a temperature sensor that checks the temperature every 100s. E.g. sleep 300s and waking up to connect to the AP (taking about 0.3~1s), the overall average current is less than 1mA.

Esp32 Timer Example
That means when you power on the esp32 it takes aprox. 0.3 seconds to arrive to the startTime first measurement. It does his update, with internet sync or not depending on the hour, and at the end measures endTime. So it discounts that time to the next sleep round plus our correction time that we called microsBootPrediction.
Apr 19, 2020 · MQTT is a good solution for this project because messages can be quickly pushed into a queue and the ESP32 can go back to sleep fast. In average one message push takes between 1.5s- 2s before the ESP32 enters deep sleep mode. If you have git installed then do a git clone https://github.com/squix78/esp32-door-sensor
