Introduction to the project:
Network of wireless sensors in the acquisition of data in greenhouses
Agriculture worldwide is influenced by the new technological paradigms; therefore, it is favored by the enormous advances in Information Technology and Communications. Precision agriculture arises with the development of new technologies aimed at agribusiness, defined as the use of a set of technologies for the monitoring of physical, chemical and climatic conditions of the crop in order to optimize the use of resources in the production process and the final quality of the products.
One of the most popular technologies in precision agriculture is wireless sensor networks (WSN), mainly due to their ability to be deployed in inaccessible conditions. In recent years, numerous precision agriculture applications have been developed based on this technology as an enabling tool. In many countries such as China, Spain and India, irrigation systems have been developed using wireless sensor networks. Other research is using such systems for monitoring environmental parameters. This is due to the low price of their implementation and minimum energy consumption, as well as the performance achieved with their use.
The collection of information, monitoring and evaluation of a cultivation system is crucial for effective decision making. In turn, decision making improves or corrects production to achieve the necessary supply, even more so when inadequate management of water resources compromise this need. This is a challenging approach to decision making, especially in complex processing environments, such as agriculture, due to its strong stochastic character.
In Cuba, the greenhouse lacks an automated monitoring system for the control of environmental parameters inside the houses. This process is carried out through the expertise of their workers and empirical estimates. This way of carrying out production is "functional", but it does not guarantee maximum safety or quality of the crops, taking into account the environmental parameters inside the houses. For this reason, investment programs have been developed for the manufacture and acquisition of modern equipment that integrate new technologies of automation, control and communications, with the aim of developing a sustainable and productive agriculture. This project aims to design the hardware and software architecture of a wireless sensor network, which allows the acquisition of environmental variables of interest for decision making in the production of plants in greenhouses.
