A new RTC clock module from Alsrobot is the sensor based on clock chip DS1307 with built-in power induction circuit to realize power failure detection and battery switchover, it also have the fuction of low power consumption and automatic time adjustment, such like in leap year RTC clock module can adjust the number of days automatically.The zone bit of AM/PM on the module determines that the working mode of the clock is 12 or 24 hours. RTC clock module adopts IIC interface,it can connect with Arduino controller and compatible with many fuction library, so user can provide accurate system time without complicated programming when developing products.
