The specific requirements of CDC for temperature monitoring of vaccine storage refrigerator include real-time data uploading and SMS alarm.

In order to ensure the safety and effectiveness of the vaccine, it is necessary to preserve it properly according to the requirements of different storage temperatures (such as refrigeration temperature of 2-8℃, freezing temperature below -20℃, ultra-low temperature). In practice, if the refrigerator door is not closed tightly, the power supply is cut off and the refrigerator is not cooled, the refrigerator temperature will not reach the optimal temperature for vaccine storage. Temperature monitoring is just uploading data, and it can't play a substantive role. After all, no one has been staring at the data. SMS alarm and acousto-optic alarm can remind medical staff to deal with and solve emergencies in time. Now this kind of temperature monitoring system is very common, which solves the trouble of nurses recording every few minutes. There are also many manufacturers. We use a product traced by Hangzhou, and we can check the monitoring situation directly on the mobile phone.
