In view of the fact that farms are often located in remote areas

Zig Bee technology can not adapt to the problem of long-distance information transmission. Using narrow band Internet of things（ NB-IoT） transmission and multi-sensor information fusion technology

a low-cost

low-energy consumption and wide coverage intelligent detection system for livestock is designed. The system consists of three parts: the field detection and control terminal

the cloud platform for NB-IoT

the mobile app and the web page. It can effectively realize the automatic collection and control of the environment. The system can be used to complete the detection of livestock breeding data accurately and complete the function of environmental automatic adjustment of equipment status according to the instructions

which has a certain application value for optimizing the management of aquaculture practitioners.
