Переводим микроконтроллер ESP 8266 в deepSleep (глубокий сон) – режим энергосбережения.
На моем контроллере NodeMcu для работы deep sleep нужно установить перемычку между RST и DO.

Идет TEST потребления deep sleep energy saving с интервалом сна -15 минут: прошло 30 часов – потребил: 0мА

В скетче устанавливаете время сна микроконтроллера, (в данном режиме все процессы, кроме отсчета времени прекращаются).

Полезно при питании микроконтроллера ESP8266 (deep sleep ) от POWER BANK, аккумуляторных батарей или просто батареек.
