Description

technical field [0001] The invention relates to the technical field of facility agriculture automation, in particular to a WSN-based photovoltaic greenhouse monitoring system and construction method. Background technique [0002] The annual operation and management of the existing greenhouses in our country consumes a lot of energy, especially in the summer when the temperature needs to be cooled and in the winter when it needs to be kept warm and heated, resulting in high energy consumption and high operating costs, which directly affect the efficiency of the greenhouse. How to reduce the energy consumption cost of greenhouse operation is the key to the current annual operation of greenhouses. The use of photovoltaic power generation by solar cells to provide green energy for the cultivation of greenhouse flowers and vegetables and the growth environment control system, thereby saving energy and reducing consumption, and improving the annual operating efficiency of the gree...
