Refrigerator wireless temperature and humidity monitoring program

I. Project background

The state stipulates that disease prevention agencies shall not only comply with the 'Pharmaceutical Business Quality Management RegulationsIt is pointed out that the CDC should use temperature and humidity monitoring equipment to monitor and record the temperature of the refrigerators/freezers/cold storage and other equipment used; moreover, the equipment should be placed in the middle of the refrigerator compartment and freezer compartment of ordinary refrigerators, and the bottom of the ice-lined refrigerator and its proximity At the cover, the middle position of the low-temperature refrigerator, 24h real-time temperature monitoring and recording are performed.

Currently, most CDCs in China use thermometers to monitor the temperature of refrigerators (including ordinary refrigerators, ice-lined refrigerators, and low-temperature refrigerators). Thermometer monitoring is time-consuming, laborious, and easy to neglect, which may cause unnecessary losses. Therefore, the 'Refrigerator Wireless Temperature and Humidity Monitoring Solution' was proposed to provide a reliable guarantee for the storage of vaccines/bloods/medicines/test samples.
