Cloud Based Smart Food Quality Monitoring System

Abstract : The evolution of multipurpose sensors over the last decades has been investigated with the aim of developing innovative devices with applications in several ?elds of technology, including in the food industry. The integration of such sensors in food packaging technology has paved the way for intelligent food packaging. These integrated systems are capable of providing reliable information about the quality of the food products during their storage period. To accomplish this goal, intelligent packs use a variety of sensors suited for monitoring the quality and safety of food products by recording the evolution of parameters like the quantity of pathogen agents, gases, temperature, humidity and storage period. This technology, when combined with IoT, is able to provide a lot more information than conventional food inspection technologies, which are limited to weight, volume, color and aspect inspection. The original system described in this work relies on a simple but effective method of integrated food monitoring, right at the client home, suitable for user prepared vacuum-packed foods. It builds upon the IoT concept and is able to create a network of interconnected devices. By using this approach, we are able to combine actuators and sensing devices also providing a common operating picture (COP) by sharing information over the platforms. More precisely, our system consists of gas, temperature and humidity sensors, which provide the essential information needed for evaluating the quality of the packed product. This information is transmitted wirelessly to a computer system providing an interface where the user can observe the evolution of the product quality over time.
 EXISTING SYSTEM :
 The research theme food quality and safety management addresses topics like food safety culture effectiveness of auditing; food handler compliance behavior safety governance and FSMS performance in emerging countries; effectiveness supplier control systems control systems for particular foods. In Existing system there is no proper food quality maintained by private hotels and schools so the quality less food served to people .
 DISADVANTAGE :
 A food contamination can occur in the production process, but also a large part caused by the inefficient food handling because of inappropriate ambient conditions when the food is being transported and stored. There are many factors leading to food poisoning, typically changes in temperature and humidity are important factors.
 PROPOSED SYSTEM :
 The Quality of the food needs to be monitored and it must be prevented from rotting and decaying by the atmospheric factors like temperature, humidity and dark. We present a new method, suitable for food quality management by wirelessly monitoring pH level changes in food with a flexible pH sensor embedded in a battery less radio-fre-quency (RF) transponder. The wireless sensor tag includes a flexible pH sensor based on miniature iridium oxide (IrO x) and silver chloride (AgCl) sensing electrodes integrated on a deformable substrate, and battery less wireless communication circuitry. It allows any node to freely join or quit the network. All nodes have equal rights in the chain, with a collective maintenance of one chain by the whole network making it a decentralized network.
 ADVANTAGE :
 It serves the purpose of preventive consumer health protection by maintaining the required standard ambient conditions needed to preserve the quality of food. The performance and analysis of routine measurements, aimed at detecting changes in the nutritional or health status of the food doesn't guarantee. For the purposes of planning, policy analysis, program evaluation and trend forecasting. Information collected through monitoring and surveillance must be analyzed and transmitted to decision-makers in an appropriate format and in a timely fashion if it is to be of real value.
