Abstract
The paper presents a low-cost solution for managing HVAC (Heating, Ventilation, and Air Conditioning) systems using an ESP32 microcontroller as the primary control unit. The proposed system integrates multiple DHT temperature sensors and actuators, such as relays, to regulate heating, cooling, and ventilation within a residential environment. The ESP32 hosts a web-based application that enables users to monitor and control the HVAC system in real-time, offering an intuitive interface accessible via any device connected to the home network. By automating the HVAC operations based on real-time data, this solution not only provides convenience but also enhances energy efficiency by optimizing temperature control and reducing unnecessary power consumption. This affordable and user-friendly system demonstrates the potential of IoT technology in creating efficient and accessible home automation systems, making it an attractive option for homeowners aiming to reduce costs and improve climate control within their living spaces.
