This is often implemented using additional counters and registers that are incremented by the 1 Hz signal. ![]() Most real-time clock modules also include a calendar function, which allows them to keep track of the current date and time. This allows the time and date to be maintained even when the device is powered off. The counter is also connected to a set of registers that keep track of the minutes, hours, days, etc.Ī battery is also connected to the real-time clock module to provide power to the circuit when the primary power source is unavailable. This frequency is then divided to create a 1 Hz signal, which is used to increment a counter that keeps track of the seconds. How does a real-time clock module work?Ī real-time clock module uses a quartz crystal oscillator to generate a precise frequency, typically 32.768 kHz. It can be used in various applications such as data logging, time stamping, alarms, schedules, and synchronization. These modules are commonly used in embedded systems and devices that need to maintain accurate timekeeping, even when not connected to a power source. It is typically a small electronic circuit that includes a quartz crystal oscillator, a battery, and an integrated circuit that retains track of the time and date. What is a real-time clock module-2?Ī real-time clock module is a device that keeps track of the current time and date even when there is a power interruption. The RTC module can be battery-backed so that it can continue to keep time even when the main power to the device is interrupted. RTC modules can also be used in various other applications, such as time and attendance systems, industrial automation systems, and home automation systems. In embedded systems, RTC modules synchronize events and trigger actions at specific times. They are essential or valuable in various applications, such as computers, servers, Arduino, and embedded systems, where accurate timekeeping is essential.įor example, in servers and computers, the RTC is used to keep track of the time of the last system shutdown and to schedule regular maintenance tasks. Real-Time Clock Modules are electronic devices that keep track of the current date and time even when power is not applied to the device.
