Iot-Based Remote Monitored and Operated Energy Efficient Multipurpose Greenhouse

Abstract

Greenhouse climate is a non-linear and uncertain system consisting of several major environmental factors such as temperature, humidity, light intensity and CO2 concentration. To control these factors a complex control system with several actuators working in coordination is designed. This project work aims at minimizing the energy consumed by the actuators used in greenhouses. To achieve this, a method to control the speed of single-phase induction motors used in fans/ ventilators is implemented, as they are predominantly the most energy consuming unit in a greenhouse. The speed of the motor is varied in accordance with the varying parameters inside the greenhouse. Parameters considered in this project are temperature and humidity. Furthermore, an efficient mode of remote monitoring of greenhouse parameters is also proposed. Greenhouse ambient temperature and humidity values from the sensor unit are sent to an IoT (Internet of Things) platform. An application is developed to enable monitoring of parameters and facilitating their control remotely. © 2024 Nova Science Publishers, Inc.
