Design Of Vegetable Greenhouse Monitoring System Based On ZigBee And GPRS

China is a country with a large population,and the development of agriculture is of great importance.At present,the demand for the quality and production of the agricultural products is constantly improving,but the traditional agricultural production mode has not been able to meet this demand.In order to monitor environmental indicators,the traditional agricultural production mode needs to lay a large number of cables in the soil,which is complicated and difficult to maintain after wiring.In addition,this kind of wired transmission has certain restrictions on transmission distance and poor anti-interference ability.ZigBee technology is an important part in the wireless sensor network technology of wireless communication technology,it provides the latest solution for the intelligent management of agricultural production,and solves many problems caused by cable transmission of the greenhouse monitoring system.It has great application prospect and practical significance.In order to better meet people's demand for vegetable greenhouse environment monitoring,this article designed a kind of vegetable greenhouse monitoring system based on ZigBee and GPRS,the system will be combined with wireless sensor network(WSN)technology and GPRS technology,realizing the function of data acquisition,wireless transmission,remote communication and monitoring.The system builds ZigBee network to realize the wireless transmission of temperature,humidity,light intensity and carbon dioxide concentration,and then using GPRS to transmit the data to the remote monitoring center,finally realizing remote monitoring of environmental index of vegetable greenhouse.The system selects CC2530 chip to design ZigBee node circuit,realizing wireless network communication,using SIM900 A GPRS module to achieve remote communication and using the Visual Studio software to write the monitoring interface,thus the user can monitor the data on the upper computer.From the test proves that the system has the advantage of high accuracy,easy operation and high operational reliability,the system can be widely used in agricultural production.
