The Design Of Greenhouse Environment Monitoring System Based On ZigBee Technology

In the agricultural production, temperature, humidity, light intensity, soil temperature and humidity, carbon dioxide concentration on environment factors in the growth of plants plays a vital role. In traditional agriculture, these pieces of information are got by eyes, lack of quantitative data, and experience accumulation and inheritance is also caused many problems. These factors greatly restricted the development of agriculture, affect the growth of plants quality and to reduce the crops of economic benefits, enable our agricultural production at low level for a long time.In view of this, this design using ZigBee technology to develop a greenhouse monitoring system. This system contains terminal acquisition node, terminal control node and data collection node. Acquisition nodes can real-time accurate acquisition crops growth environment air temperature, air humidity, light intensity, soil temperature, soil moisture, carbon dioxide concentration on the environmental elements, through wireless self-organizing networks , these data are sent to the server to storage and analysis. Through wireless communication module complete network to join and exit, sensor numerical upload and various orders of receiving work. By using the data acquisition module finish all kinds of sensor data collection and data packets. By using the human-computer interaction module completing the user operation of input and output of information system. By using the power monitoring and control module completing system power supplies power monitoring and sensor power control. By using the system configuration module implements this user remote node certain parameters allocation function. Control node can send the equipment running status uplink information (current equipment in open or closed) to data collection node, also can receive data collection control commands from node downlink open or close corresponding equipment.We completed the three nodes design of the software and hardware, and tested in accordance with the design requirement.
