PRODUCT DESCRIPTION
This module is a Tiny RTC Real Time Clock DS1307 I2C IIC for Arduino. It has a DS1307 real-time clock IC and a backup battery. You can easily use it with Arduino and other libraries, or just use I2C commands to set and get the time and date. The module comes with a lithium coin cell battery that should last for at least four years.
The module also features an Atmel 24C32 EEPROM chip, which is useful for storing data without worrying about power loss. You can also solder your own DS18B20 temperature sensor on the board.
This clock module can keep a reasonably accurate time even when your Arduino is off. It is very handy for data logging and other time-sensitive applications. The device uses I2C to communicate with your Arduino.
Note: Battery is not included in the package, you need to buy it separately.
