 There is a modification to be made – both in hardware and software – to get current consumption low. On the firmware end, the Espressif SDK has made a ''​system_deep_sleep([uint32_t time_in_us])''​ function available, which puts the ESP8266 to sleep for a specified number of microseconds. When it wakes up, it begins running the user program from the very beginning. If you’re using the ESP8266 Arduino IDE, they’ve wrapped that function and another into a very nice ''​ESP.deepSleep([microseconds],​ [mode])''​ function. Here’s a quick example Arduino sketch for the ESP8266 that blinks the on-board LED 10 times, sleeps for 60 seconds, then repeats. There is a modification to be made – both in hardware and software – to get current consumption low.
