Project description:
This project uses 16F628A as the microprocessor, TC-77 for temperature sensing and 24LC64 as storage device. The objective is to create a low power temperature recoding device. The entire device consumes 400uA of current. The power is supplied by a standard battery pack (3.6V) for cordless phone. Lower power comsumption is possible if the shutdown code is implemented for the TC-77 temperature sensor, however, due to the time limitation, it is not available in this version of the code.

Electronics used:
TC-77
24LC64

Link: Temperature recoding device
