Design and Implementation of a Cold Chain Temperature and Humidity Monitoring System
Aiming at the problems of low automation and poor real-time performance in the process of cold chain temperature and humid-ity monitoring,a real-time cold chain temperature and humidity monitoring system based on Internet of Things(IoT)and cloud platform is designed.PT1000 and AM2120 sensors are selected as the information acquisition part of the system,LPC824M chip is used for data processing,and the high-speed communication between the detection system and the host computer is realized with the wireless commu-nication module of BC28 chip and Alibaba cloud platform.The experimental results indicate that the system has the characteristics of low power consumption,long service life and stable operation.It can realize the real-time monitoring of temperature and humidity in the cold chain system.The system has the advantages of convenient installation and low cost.It can monitor the environmental temperature and humidity change state of the cold chain system in real time and accurately,so as to avoid the loss of the cold chain system caused by the drastic change of temperature and humidity.
