Design and Implementation of an Intelligent Monitoring System Based on ZigBee for the Agricultural Greenhouse

Abstract

This paper describes an implementation of the Internet of things technology to the agriculture production, aiming to design and realize an intelligent monitoring system based on ZigBee a wireless communication technology, in a handmade greenhouse model. In this paper, we also design a control node based on ZigBee, which can control the multiple control equipments in the greenhouse. The system collects the environmental parameters in the greenhouse through a variety of sensors, such as the soil temperature and humidity, the air temperature and humidity, and the light intensity. By applying ZigBee, the collected environmental information is transmitted to a sink node and finally to the monitoring center. The center analyzes the collected parameters and then sends commands to the control node according to the control strategy or sends some warning short messages to the mobile user. According to the received commands, the control node will turn on or off the environmental control equipment in the greenhouse. For example, the control node can turn on or off the exhaust fans to regulate and control the corps’ growing environment, which realizes an intelligent agriculture production. The center also provides the remote access mode for users to obtain the real-time environmental parameters and the monitoring videos, which helps the intelligent controlling of various equipments to adjust the corps’ growing environment in the greenhouse.
