DS1302 Real Time Clock (RTC) Module
The DS1302 Real-Time Clock (RTC) module is designed to keep accurate time, much like a traditional watch. It utilizes a precise oscillator and requires a small battery (not included) to maintain time even when the power is off. This module is perfect for applications where accurate date and time are crucial, such as attendance systems, digital cameras, automated sprinkler systems, and time/calendar displays. With its reliable timekeeping, the DS1302 RTC is an excellent choice for time-sensitive projects.
