Abstract: Objective To improve the monitoring of refrigerator operation, the quality control and management of equipment, and the management of drug safety. Methods Based on wireless transmission technology, through employing temperature and humidity sensors and setting monitoring indicators, the temperature and humidity data were automatically monitored, collected, and uploaded in real time. Results It solved the problems of inaccurate refrigerator temperature monitoring, wrong transcripts, and untimely feedback in the departments of a tertiary class A hospital. It realized 24-hour real-time monitoring and early warning, reduced the workload of temperature and humidity management, and lowered management risk. Conclusion The study findings can meet different needs on cold chain monitoring of various departments of the hospital, especially the cold storage management of drugs in pharmacy departments and the cold storage management of samples in laboratory departments.
