The DS3231 is a low-cost, highly accurate Real Time Clock which can maintain hours, minutes and seconds, as well as, day, month and year information. Also, it has automatic compensation for leap-years and for months with fewer than 31 days.
The module can work on either 3.3 or 5 V which makes it suitable for many development platforms or microcontrollers. The battery input is 3V and a typical CR2032 3V battery can power the module and maintain the information for more than a year.
Once we connect the module we need to program the Arduino Board to work with the Real Time Clock. However, when it comes to programing a communication between Arduino and an I2C module the code isn’t that small and easy. Luckily, there are already several libraries for the DS3231 RTC which can be found on the internet.
The module uses the I2C Communication Protocol which makes the connection to the Arduino Board very easy.
