Greenhouse Environment Monitoring and Control System using CoAP
Junsung Park, Hyun Yoe · Advanced science and technology letters · 2015
Environmental control of greenhouse is a part that plays an important role in creating the internal environment and focuses on meeting the optimal environmental conditions in the greenhouse. Most domestic greenhouses are to collect sensor data by installing a sensor at a point and control the environment. However, in order to create an optimal environment, the environment should be created by collecting precise environment data for the entire greenhouse but an economical way is required because a lot of costs and sensors are needed. In order to secure a communication environment that is limited in performance and memory with application layer protocol being made by IETF CORE(Constrained RESTful Environments) Working Group, power consumption between sensor nodes is saved by applying a method focused to network M2M for low power with CoAP(Constrained Application Protocol) protocol. A system which is more efficient by being applied to the greenhouse environment monitoring and control system and simply applied through the implementation in the layer without changes in the sensor node that was using existing ZigBee is studied.
