Product details

The DS1307 module is an accurate I2C real-time clock (RTC) with an integrated temperature quartz oscillator and crystal. The module must be powered by a rechargeable buffer battery to maintain time during power interruptions. The date is automatically adjusted, and leap year corrections are also taken into account. The module offers two configurable alarms and a calendar. Address and data are transmitted bidirectionally via an IIC or I2C bus. It features a highly accurate digital temperature sensor that can be queried through the I2C interface. You can find a suitable library for controlling the DS1307 clock in the Arduino Library Manager, which you can install.
