There are a large number of products that need cold chain logistics in the fields of food, medicine, blood products and biological products which are related to life safety and health.
In order to strengthen effective management and control, the authorities had issued relevant laws and regulations requiring temperature monitoring in the whole process of cold chain, and storing, recording, encrypting, uploading and checking relevant information, so as to realize all-electronic traceability in the whole process.
Cold chain logistic traceability has different implementation methods due to different requirements. for present, is difficult to realize all-electronic traceability with high temperature accuracy and low cost. The wireless temperature sensing SoC PL51NTXX series of POWERLINK provides an ideal solution.
Series Chip of POWERLINK
This series of chips is tailored for cold chain logistic traceability, and its performance has reached the international advanced level. And meets ultra-low cost.
