## Key points

- The study developed an inventory management system for a photovoltaic-powered freezer
- A wireless sensor network was used to promote energy efficiency and responsible food use
- An Arduino-based wireless network of sensors on a solar-powered freezer was used to develop the smart inventory management system
- Perishable and non-perishable items can be monitored remotely without having to physically check inside the freezer
- An Android application was developed to receive and display data sent from the sensor network through GSM Shield SIM800L
- This approach promotes sustainable practices and improves inventory management efficiency in freezers.

## Summary

The International Journal of Emerging Trends in Engineering Research published a study by Janus Jade A. Basa and colleagues from the Department of Electronics Engineering at the Technological University of the Philippines, Manila. The study developed an inventory management system for a photovoltaic-powered freezer using a wireless sensor network to promote energy efficiency and responsible food use. The system uses an Arduino-based wireless network of sensors on a solar-powered freezer to develop a smart inventory management system that is accessible and easy to use. By implementing this network of sensors inside the freezer, perishable and non-perishable items can be monitored remotely without having to physically check inside the freezer. Furthermore, an Android application was developed to receive and display data sent from the sensor network through GSM Shield SIM800L. This approach not only promotes sustainable practices but also improves inventory management efficiency in freezers.
