Product Description :
A real-time clock (RTC) module, such as the DS1302, functions similarly to a watch. It uses a precise oscillator and a small battery (not included) to keep accurate time. Many applications require an accurate date and time, such as attendance systems, digital cameras, automated sprinkler systems, or time and calendar displays. The RTC module is ideal for these time-critical applications.
