Cai et al.: Designing an intelligent greenhouse monitoring system based on the internet of things -8449 -APPLIED ECOLOGY AND ENVIRONMENTAL RESEARCH 17(4):8449-8464. Abstract. With the development of the Internet, the development of the Internet of Things (IoT) has also been promoted. The IoT is a network of "objects and objects connected." The IoT is based on cloud computing platforms and wireless networks. It acquires data based on sensor groups and conducts decision analysis to change the

The IoT has subverted the traditional agricultural production model, from the agricultural farming model to the "smart agriculture" production-operation-sales model, which provides a direction for the sustainable development of agriculture in China at this stage. Based on the IoT and Zig Bee wireless sensor network technology, this paper designs a general scheme of an intelligent greenhouse control system based on IoT technology. The greenhouse control strategy was studied using IoT technology and fuzzy adaptive PID control algorithm. The experimental simulation was carried out with MATLAB software. The simulation results show that the optimal control of greenhouse temperature is achieved. The temperature in the greenhouse is always maintained at 16.5 °C -23.0 °C, and the humidity value is always maintained at 68.2% RH-89.3% RH. The test verified that the paper can achieve the expected effect for the greenhouse.

IoT technology is the product of the development of new generation information technology, and has been highly valued and widely used in wireless communication applications. The IoT is generally combined with Zig Bee wireless sensor network technology ( Espinosafaller, 2012), which is a short-range, low-rate wireless communication technology. The name of Zig Bee comes from the body language of the bees. When the bees find pollen, they will dance in a zig-zag motion. Through this splay, the message of the pollen's position and distance will be transmitted to the companion. It was formerly known as "Home RF Lite" or "Fire Fly" communication technology for wireless communication at close range (Yusof et al.
