ABSTRACT This paper introduces a smart management system designed for cold storage facilities. Our goal is to monitor environmental conditions in real time and automatically manage equipment to maintain ideal storage settings. The system uses modern sensors to track important factors like temperature, humidity, and gas levels. If any of these go beyond safe limits, the system immediately notifies the user and takes action to correct the situation. It also includes features like automatic control of cooling and dehumidification through relays and ensures uninterrupted performance with a battery backup during power cuts. Additionally, the system is built to save energy by adjusting cooling based on environmental changes and time of day. Users can monitor and control the system through a mobile app or web dashboard, making the entire process convenient and reliable.
