DS3231 is a low-cost, extremely accurate I2C real-time clock
(RTC), with an integrated temperature-compensated crystal
oscillator (TCXO) and crystal.
The device incorporates a battery input, disconnect the main
power supply and maintains accurate timekeeping.
Integrated oscillator improve long-term accuracy of the device
and reduces the number of components of the production line.
The DS3231 is available in commercial and industrial
temperature ranges, using a 16-pin 300mil SO package. RTC maintains
seconds, minutes, hours, day, date, month, and year
information.
Note: This is not original Arduino product. it only a
substitute accessories from WINGONEER

Save time and high precision addition, DS3231 also has some other
features that extend the system host of additional features and a
range of options. The device integrates a very precise digital
temperature sensor, through the I2C * interface to access it (as
the same time). This temperature sensor accuracy is ±3°C. On-chip
power supply control circuit can automatically detect and manage
the main and standby power (i.e., low-voltage battery) to switch
between the power supply. If the main power failure, the device can
continue to provide accurate timing and temperature, performance is
not affected. When the main power re-power or voltage value returns
to within the allowable range, the on-chip reset function can be
used to restart the system microprocessor.
