Design of Greenhouse Temperature and Humidity Monitoring System Based on ZIGBEE Technique

摘要

Based on ZIGBEE technique, this paper designs a monitoring system of environment parameters in greenhouse. ZigBee technique is firstly introduced, followed by the demonstration of overall design scheme of the monitoring system, mainly on the hardware and software composition of data acquisition and coordinator nodes whose core is CC2530, and on the work principle of temperature and humidity sensors and circuit design. Detailed analysis is made on the program design of every module. Test results show that all data nodes function well and can collect appropriate parameters with negligible errors; the wireless networking of all sensor and coordinator nodes works properly and can be used to transfer data, meeting the system design requirements. Therefore, it is proved that the system design is practical.
