Abstract
Greenhouses are crucial elements of contemporary farming methods that enable the year-round production of crops under carefully regulated climatic conditions. Conventional manual control of greenhouse parameters and power management are laborious and inefficient. Therefore, this study designs a control system for intelligent power management of a greenhouse, implement the proposed design and evaluate the performance of the system. The system comprises the current sensor, temperature and humidity sensor, soil moisture sensor, Light Dependent Resistor (LDR) for monitoring the temperature, humidity, soil moisture and light intensity. As the central control unit, the ESP32 microcontroller processes data from various sensors and makes decisions in real time to modify the greenhouse's operations, including the watering, lighting and cooling systems that are necessary for the sustainability and growth of the plants. Using the Internet of Things, real-time remote monitoring and control was incorporated to enable users to modify environmental parameters without physically present in the greenhouse. The study outcomes revealed that the temperature was effectively kept between 23°C and 27°C, the humidity level was maintained between 65% and 80% and the soil moisture content maintained between 60% and 80% which are ideal for growing tomatoes in greenhouse. Result further shows that the farmer can monitor and modify environmental parameters within the distance of 35 to 40 meters away from the greenhouse and the greenhouse's optimal energy utilization was achieved as a result of components’ operation as needed. The applied control system could give tomatoes nursery plants a steady and regulated environment resulting in more consistent and healthy growth
