Abstract
To satisfy the requirement of the control parameters in greenhouse, this paper introduced the design scheme of monitoring and control system based on Zigbee due to its low-cost, simplicity and mobility. We designed the sensor node, control node and gateway node based on CC2430, described the design method of hardware circuit and the flow chart of software. By monitoring the environment factors in real time, such as illumination, temperature, humility and carbon dioxide, the spray system, ventilation fans and lighting lamps were automated controlled to satisfy crop growth requirement. The monitoring system is easy to expand and update, and the program interface is friendly to operate.
