DS3231 is a Real-time clock module which primarily triggers the clock pulse. DS3231 has some special feature which comes handy in many ways, the most important one is that it has its own battery which helps to keep track even if the device power shuts down. DS3231 is highly accurate while measuring and it can measure in seconds, minutes, hours up-to years, also it can keep records of days, months and year information.
DS3231 becomes very handy when it comes to leap-year compensation. DS3231 is a low cost and energy-efficient module that can communicate through serial communication which is perfect for any kind of device/Project.
