A voltage detector is handy for projects where you want to make sure your microcontroller doesn't run at a low voltage. For example, say you have a Feather Huzzah running on a lipoly battery every few minutes. Eventually, the battery runs down and goes below 3.3V, so the voltage to the ESP8266 core is too low, and could cause a lockup or corrupted data....
