I2C RTC DS1307 AT24C32 Real Time Clock Module For AVR ARM PIC

This is a great battery-backed real time clock (RTC) that allows your microcontroller project to keep track of time even if it is reprogrammed, or if the power is lost. Perfect for datalogging, clDS1307ock-building, time stamping, timers and alarms, etc. The DS1307 is the most popular RTC, and works best with 5V-based chips such as the Arduino.


  • Brand new and high quality.
  • This is the DS1307 Real Time Clock developed by one of our designer.
  • The module comes fully assembled and pre-programmed.
  • The DS1307 is accessed via the I2C protocol.
  • Two wire I2C interface.
  • Hour:Minutes : Seconds AM/PM.
  • Day Month, Date – Year.
  • DS1307 based RTC with LIR2032 battery (Battery include).
  • 1Hz output pin.
  • 56 Bytes of Non-volatile memory available to user.
  • Item size: 28*26*8mm
  • Net weight: 7g

Note: The DS1307 is simple and inexpensive but not a high precision device. It may lose or gain up to 2 seconds or more a day. For a high-precision, temperature compensated alternative.

  • I see in the MainWindow.cs file there is an array of integers caleld Histogram and a corresponding UpdateHistogram() Method which takes a DepthMetaData parameter but I don’t see any documentation that describes what they are doing or why. What exactly is the of the Histogram ? I see you give props to Vangos Pterneas for the functions so maybe you know if he has it documented somewhere? I have looked over several projects he has posted but your code is the first place I have seen this code. Nathan
