How to reduce power consumption of ESP32 in deep sleep mode?
I am building a solar-powered weather station in Kairouan using ESP32 and DHT22. How can I minimize battery drain to keep it running 24/7?

Use `esp_deep_sleep_start()` and isolate the ADC / Wi-Fi peripheral power rails before sleeping. Also disable the built-in power LED or bypass the CP2102 USB UART chip during deep sleep.
