| Summary, etc. |
This study presents the designing and development of an IoT-Based Air<br/>Conditioning Unit (ACU) intended to enhance energy efficiency, real-time environmental<br/>monitoring, and user comfort in a single-room application. The system integrates an<br/>ESP-WROOM-32 microcontroller with an AMG8833 IR Thermal Camera and an<br/>Ultrasonic Sensor for heat signature and occupancy detection, an MQ135 Air Quality<br/>Sensor, a ZMPT101B AC Voltage Sensor, and an ACS712 Current Sensor, alongside a<br/>custom mobile application for remote access and control. The research addresses the<br/>growing need for intelligent and automated indoor climate control systems capable of<br/>adapting to dynamic occupancy and environmental conditions. The prototype was tested<br/>from March 27 to April 4, 2025. The ACU successfully detected human presence within<br/>a 0.8-meter radius and adjusted room temperature from a default of 24°C when<br/>unoccupied to as low as 17°C when fully occupied, with a response time of<br/>approximately 2 to 5 seconds. The adaptive cooling logic lowered the temperature by 1°C<br/>for each additional occupant, up to eight persons. Air quality was monitored every 15<br/>minutes, with values improving significantly during periods of increased<br/>occupancy—initial readings on April 2 showed AQI values between 1.89 and 0.83 in the<br/>morning, improving to a range of 0.47 to 0.63 later in the day. The system’s daily energy<br/>consumption ranged from 6.98 to 9.12 kW-hr, achieving energy savings of up to 9.24<br/>kW-hr compared to commercial AC units, equivalent to a cost reduction of ₱120.237.<br/>The results demonstrate the ACU’s reliability, energy efficiency, and responsiveness in<br/>real-time scenarios. By integrating IoT functionality with automated temperature<br/>adjustment, environmental sensing, and mobile-based monitoring, the system offers a<br/>practical and sustainable solution for smart home applications focused on user comfort<br/>and operational efficiency. |
