基于Zigbee的温室环境监控系统设计

DESIGN ON MONITORING AND CONTROL SYSTEM FOR GREENHOUSE BASED ON ZIGBEE

为了无线、实时监控花卉温室的温度、湿度、光照等参数,本文以STC89C52为控制器,利用无线通讯模块CC2530、温湿度传感器DHT11、光照模块GY-30、步进电机28BYJ-48、液晶模块1602等构建一种温室环境监测系统硬件电路,根据硬件电路设计相应的主程序,检测子程序,无线通讯子程序等。最后设计制作了样机,测试结果表明,该系统人机交互性较好,传输数据稳定,控制效果满足要求,成本低廉,使用方便,适用于花卉温室的环境监测。

In order to realize wirelessly and real-time monitoring parameters such as temperature, humidity, illumination for 0 flowersgreenhouse,Witli a single-chip microprocessor STC89C52 as the control core, a wireless monitoring and control system is consisted ofwireless communication module CC2530,temperature and humidity sensor DHT11,light module GY-30, stepper motor28BYJ-48 and LCD module 1602 , etc. Then this paper design the corresponding main program, detection subroutine, wireless communication subrou-tine based on hardware design , etc. Finally, a prototype ii produccd and the test results indicate greenhouse environment monitoring as it has good man-machine interaction , Stable transmission performanlowcost and simple operation.
