COLD STORAGE CONTROL SYSTEM USING IOT

Abstract

Cold storage is one of the important tools for many kinds of distributors, pharmaceuticals to connect with
markets and to realize meaningful productivity. Due to lack of cold storages and lack of information about the current
temperature in the cold storages, many distributors are unable to save their produce for future sellers, hence causing
sharp price dips. A dearth of continuous electricity, absence of any warning systems, and the ratio of the wastage
product will increases. A smart Iot connected device which acts as a data acquisition device and a controller serves the
problem solution. The health status of the cold storage can be viewed using a web application or mobile application in
almost real-time. The system detects risky scenarios and provides early warning notifications in critical conditions. In
this technology advancement, everything requires monitoring and controlling. This paper proposes an Iot framework
for facilitating food monitoring for protection of the food, so that it would not get contaminated due to surrounding
conditions during storage. In present scenario, the work done is in terms of the sensed values that have been recorded
and a detailed analysis has been performed but automated control alternatives are not present. The proposed solution
analyzes temperature, moisture as these parameters affect nutritional values of food items and makes the analysis
results accessible to the user via a web server. A web server is used for storage of data values sensed in real time and
also for analysis results. User is alerted whenever an emergency occurs. In this solution, sensor for various domains is
employed for sensing the condition of food. The data values with plotting of graphs have been done at remote
location. So that this data can easily be used for further analysis and the user could be notified if a change in
parameters values above a threshold is recorded.
