In order to improve the technology level of large-scale pig breeding and reduce the work intensity of monitoring by human beings,pig disease monitoring and early warning system is designed based on the internet of things using the application of NB-IoT and 2.4 GHz ISM technology,which realizes the functions of environmental temperature and humidity measurement,pig identification,temperature collection and movement status recording,remote health monitoring and epidemic warning.This system provides a new solution of low cost,low power consumption and high efficiency for fully automated management,remote monitoring,epidemic detection and food safety of the aquaculture industry,which can effectively improve the breeding level and economic benefits of large-scale pig industry.
