When transporting food and pharmaceuticals the focus is on the strict maintenance of temperature and humidity mode and hygiene requirements. Only special transport equiped with refrigerators and control devices should be used in this case.
Our company has experience in implementing systems of monitoring temperature and humidity at all stages of delivery process from producer to consumer. This monitoring system consists of data loggers (registrators) which control different parameters: temperature, humidity, carbon dioxide concentration, etc. Parameters are measured and recorded with the help of both internal (air temperature, CO2) and external sensors (product temperature, air humidity).
Logger or loggers' net is connected to PC via adapter from time to time depending on the need to read the accumulated data or change the settings. The read data is stored in the database on the user's computer or server. A user can draw graphs and data tables and make reports based on the data.
A lithium battery and non-volatile memory provide autonomous data record to the logger memory during a long period: from several weeks to several years.
