基于GPRS的温室大棚温湿度监控系统的设计

GPRS-Based Designing Temperature and Humidity Monitoring System of Greenhouse

采用89C51单片机、GPRS模块SIM300、温度传感器AD590、湿度传感器HM1500设计基于GPRS的温室大棚温湿度监控系统。该系统可根据用户设定参数自动采集现场的环境数据,并根据设定温湿度极限值报警,同时采集数据经过GPRS网络传送至上位机进行存储及处理,从而实现对温室温湿度的实时监测。系统检测精度高、使用简单、成本较低,工作稳定可靠,可以降低蔬菜大棚的现场监测成本,有助于提高农作物的产量。

The temperature and humidity monitoring system of greenhouse based on GPRS using 89C51 MCU, GPRS module SIM300, AD590temperature sensor, humidity sensor HM1500 was established. The system could achieve automatically acquisition of the field environment data by setting parameters of user, and alarm according to the setting temperature and humidity＇limit at the same time. The acquisition data could be sent to the host computer through the GPRS network for processing and storage to realize real-time monitoring of temperature and humidity of the greenhouse. The whole system was typical of high precision, simple to use, low cost, stable and reliable work, which could reduce the field monitoring cost of greenhouse, help to raise the yield of crops.
