Food poisoning that can happen commonly, a little caution can be prevented in advance, but the average consumer can not know whether the poisoning infection of food. 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 proposed the food poisoning prevention monitoring system based on the smart RFID tag system. Proposed system consists of RFID tag, temperature and humidity sensor, sensor interface, RFID 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, and is monitored. The proposed system confirms usefulness through experiments.
