Food spoilage has detrimental effects both in terms of health risks for consumers as well as increased costs for producers. This prompted the development of a system for detecting food spoilage that was compact, lowmaintenance, and simple to manufacture. The design of said system is discussed in this paper. This paper proposes a design and implementation of food intelligent monitoring system based on pH sensor. The results of our paper show that it is possible to use pH sensor technology and near field communication technology to detect changes in pH to avoid food spoilage.
