Modular System for Cold Storage Monitoring

Pedro José Sousa, Manuel Rodrigues Quintas, Paulo Abreu


This work describes the development of an embedded electronic-based monitoring system suitable for cold-storage electrical equipment. The system uses a touchscreen and provides sensors for temperature, relative humidity, electric power consumption and detection of door position. To monitor the electric power, a special purpose current sensor was developed and calibrated. The system adopts a modular architecture using cabled and wireless communications, making it suitable for integration in other logging and alarm generation systems. The system was tested on a home fridge to demonstrate its capabilities.
