REFRIGERATOR TEMPERATURE MONITORING USING RFID

Food poisoning is a common, usually mild, but sometimes deadly illness. Typical
symptoms include nausea, vomiting, abdominal cramping, and diarrhea that occur suddenly
(within 48 hours) after consuming a contaminated food or drink. The known causes of food
poisoning can be divided into two categories: infectious agents and toxic agents which is can
make our food to be rotten. One of the way to prevent this is by make a good decision
during buying food from supermarket but sometime we don't even know whether the food is
good or not. Supermarket also must make sure all of their products are in good condition. As
an outcome for this problem, the author comes with a solution called `Refrigerator
temperature monitoring using RFID'. Transponder with temperature sensor will be placed in
every refrigerator in the supermarket and the transponder will keep taking the refrigerator
temperature as a data send to the reader. System from a host or computer will detect if the
data of refrigerator temperature exceed the limit (max 4.5 degree Celsius) and system will
alert the user of the system. As an interface for the RFID application, Microsoft visual basic
2008 is used and Microsoft Office Access is used for the database. ActiveWave
Demonstration Kit which is the RFID hardware chosen for this project. Besides, the system
also provides a system for reviewing and editing the details of refrigerator. This will make a
record documentation work easier. Upon completion of the project, supermarket that using
this product can monitor easily the refrigerator in their supermarket and customer will be
more satisfied. This will make all the products in the refrigerator always in good condition
and always save for customer.
