Greenhouse monitoring system based on PLC and wireless sensors

The modern monitoring and control systems that are currently used in most fields are based on intelligent algorithms, distributed management systems, and a new generation of communication buses. For the monitoring and control of the processes inside a greenhouse, the use of sophisticated algorithms or complex devices is not required. However, in order to make the activity more efficient and increase the production of a greenhouse, a proposed solution is to use data management and control devices such as PLCs, and the data acquired from the greenhouse to be retrieved by means of sensors connected to nodes with wireless transmission. The wireless communication variant proved to be the most efficient, in the greenhouse environment being an increased humidity due to the irrigation process of the plants. Also, the need for space for the plants requires giving up the wires drawn through the greenhouse.
