DESCRIPTION
This module contains a number of chipsets that fulfil a number of different roles. You will find a DS1307 real time clock (BCD), a AT24C128 EEPROM and a DS18B20 temperature sensor. This small form module makes the perfect launch pad for a weather monitoring system or similar project.
The DS18B20 is a standard module for temperature, in the case of the Arduino development environment the Dallas temperature control library is available to make use of the sensor easier.
In the case of the clock and EEPROM communication is handled through a 2 pin I2C interface, available on a wide range of microcontrollers. The I2C addresses are 0x68 for the clock and 0x50 for the EEPROM. Both use the same two lines so you only need to wire a single pair of I2C lines to your microcontroller. In the case of the temperature sensor a up to a 12 bit message is output to the DO pin. In total that is 3 pins required to access all the modules features.
Please do not hesitate to contact us if you require further information regarding the module's operation.
