摘要
在分析了传统温湿度采集设备的基础上,提出了一种以MSP430单片机为控制器,利用温湿度传感器DHT11实现对温室环境数据进行采集的系统。通过键盘和LCD1602液晶显示屏实现人机交互,利用nRF905无线收发模块将采集的数据发送到上位机,上位机通过VB和ACCESS实现对温湿度的实时监测和历史数据的保存。实验结果表明,该系统结构简单、成本较低,克服了传统采集设备布线复杂、维护困难等缺陷,而且可以实现远程监控。
This paper presents a greenhouse environment data acquisition system on the basis of the analysis of the traditional temperature and humidity acquisition device. MSP430 single chip microcomputer is used as the controller, and the temperature and humidity sensor DHT11 is used to realize the data collection. Through the keyboard and LCD1602, it realizes the human-computer interaction. The nRF905 wireless transceiver module is used to transmit data to the PC. Though VB and ACCESS, the PC realizes real-time monitoring of temperature and hu- midity and the preservation of historical data. The experimental results show that the system has the performances of simple structure, lower cost, and overcomes the faults of wiring complex, maintenance difficulties and realizes remote monitoring.
