The Design of Smart RFID Tag System for Food Poisoning Index Monitoring

Factors most affecting the health risks in the world are food poisoning such as food contamination is a disease. While there are many factors affecting food poisoning typically changes in temperature and humidity, and monitoring temperature and humidity variability during transport and storage is very important. So we for the consumer to prevent food borne illness and food poisoning index monitoring system are proposed. Proposed system consists of RFID tag, temperature and humidity sensor, sensor interface, reader, and server. In order to verify the effectiveness of the proposed system, we performed experiments on the tofu. Proposed system measures the temperature and humidity using the smart RFID tag. The measured information can be calculated according to food poisoning index with four grade, interest, caution, warning, risk. The proposed system confirms usefulness through experiments.
