What is DS1307 clock?
Maxim Integrated DS1307 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. The clock/calendar on the DS1307 provides seconds, minutes, hours, day, date, month, and year information.
What is a DS1307 module?
The module based on DS1307, The DS1307 serial real-time clock (RTC) is a low-power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially through an I²C, bidirectional bus. The clock operates in either the 24-hour or 12-hour format with AM/PM indicator.
What is real-time clock module?
HomeElectronic ModulesReal Time (RTC) Module. RTC is an electronic device in the form of an Integrated Chip (IC) available in various packaging options. The purpose of an RTC or a real-time clock is to provide precise time and date which can be used for various applications.
What are the features of real-time clock?
Features:
- Programmable square wave output signal.
- Automatic power-fail detect and switch circuitry.
- Consumes less than 500nA in battery backup mode with oscillator running.
- Available in 8-pin DIP or SOIC.
- Underwriters Laboratory (UL) recognized.
Why real-time clock is needed?
The purpose of an RTC or a real time clock is to provide precise time and date which can be used for various applications. It plays a very important role in the real time systems like digital clock, attendance system, digital camera etc. In applications where time stamp is needed, RTC is a good option.
How does the DS1307 serial real time clock work?
The DS1307 serial real-time clock (RTC) is a low- power, full binary-coded decimal (BCD) clock/calendar plus 56 bytes of NV SRAM. Address and data are transferred serially through an I2C, bidirectional bus.
How to read the time on Arduino DS1307?
It is used with the start clock command to control the module’s state. Read Clock: RTC.readClock(); After the clock is turned on using the Start command. You need to read the data from the RTC module. This is done by the readClock function. This function is essential before the latter commands can be used. Reading the time:
What are the features of the DS1307 RTC?
Some of the well-known features of the popular DS1307 RTC are mentioned below. Complete Timekeeping functionality i.e. hours, minutes, seconds, year with leap-year, month, date of the month and day of the week. Valid up to the year 2100.
Is there a time drift on the DS 1307?
The DS 1307 is specifically designed for timekeeping, The time is fairly accurate with an error (time drift) of about 1 minute per month. If u want to eliminate this u can go for the DS3234 which has a time drift of only 1 minute per year.
