Design Of Monitoring System About Agriculture Greenhouse Environment Temperature Based On ZigBee Technology

Into the21st century, people have a deeper understanding at scientificproduction and automation service, they pay much more attention on temperaturemonitoring in many fields. With the development of the agriculture greenhouse,It proposes the concept of scientific management and scientific cultivation. Sohow real-time and efficient to monitor agriculture greenhouse temperature hasbecome a key issue.The traditional monitoring ways of agriculture greenhouse temperature aremostly used to install thermometer or manual recording temperature, Theseproduced a lot of labor and financial loss to production or work. In this paper,The ZigBee technology to achieve real-time acquire and send agriculturegreenhouse temperature, The problem of greenhouse space wiring difficulties iseffective solved. So it achieves a rapid and effective to access agriculturegreenhouse-site temperature data, but also has provided a guarantee about high-quality and high demand for production and work.In this paper, the system of monitoring about agriculture GreenhouseEnvironment Temperature Based on ZigBee is made up of front-end dataacquisition, data processing, data transmission and data reception. The ambienttemperature is real-time processed by the temperature sensor of data acquisitionterminal node. Processed data is send to the intermediate node through a wirelessnetwork. Intermediate node aggregates all data, then send the data to the PCthrough a serial port, at the same time, staff may view, analysis and storage thedata by the PC, that provide real-time data for agricultural greenhouse, fans andother temperature control equipment, and achieve automatic temperature control.This paper solves the technical problems of the system hardware and software design, programming, circuits, and networking. Data were accessed andanalyzed by laboratory tests.The experiments show that this system is stable, theacquisition accuracy can meet the requirements of agricultural greenhouse fortemperature control.
