Energy-efficient autonomous greenhouse ventilation system with remote intelligent control

Abstract

The article develops an autonomous ventilation system for a greenhouse system powered by solar energy and remote smart control, which includes a solar panel, a battery and a charge controller, a fan/heater as actuators, temperature and light sensors, and a controller. At the same time, the software control logic is integrated into the Node-RED environment, implementing the reading of temperature and light indicators, an algorithm for automatically turning on/off ventilation when a given temperature threshold is exceeded, and analysis of the light level as a conditional indicator of the intensity of solar energy generation. The system provides autonomous power supply for the system by optimizing electricity consumption according to the available charge and lighting conditions. For this, it is necessary to develop a graphical interface for monitoring parameters in Node-RED, which allows the user to monitor the temperature, ventilation and power status in real time and perform system testing in a real greenhouse, assess the stability of operation, energy efficiency, and adaptability to changes in climatic and energy conditions.
