A month ago, we tested simple temperature logger with EEPROM storage. Today, we are going to do some improvements. We will use external EEPROM – EEEPROM for data storage (128×16 positions) and EEPROM as settings storage. In addition we will make a sampling period adjustable by DPA command.
Today, we are going to start first part of new serie of articles about wireless data loggers. Today, we will do simple temperature logger for short periods. This temperature logger uses TMP112 device assembled on DCTR module and stores value into MCU EEPROM.
