DS3231 Precision RTC Real Time Clock Module
A real time clock is basically just like a watch – it runs on a battery and keeps time for you even when there is a power outage! Using an RTC, you can keep track of long timelines, even if you reprogram your microcontroller or disconnect it from USB or a power plug.
