Smart Thermal Environmental and Noise Monitoring to Enhance Indoor Comfort for Classrooms: A Case Study at the International College of Auckland, New Zealand

The increasing concern about worldwide climate change will necessitate better approaches to daily life. As a result, indoor thermal comfort and air quality in school classrooms have become a global priority to improve air quality in educational settings. In this paper, indoor air quality parameters and noise levels were studied and monitored using an Arduino Uno R3, equipped with a sound sensor, CO2 sensor, and environmental and humidity sensors to control indoor quality. The performance of the smart thermal environmental and noise monitoring system was evaluated in a typical classroom at the International College of Auckland (ICA) in New Zealand. Mechanical analyses were conducted using HAP software for the classroom, showing that the room requires a 2-ton ceiling air conditioning unit. Parameters were monitered effectivelly, and the hardware controlled the indoor colling system well. The results demondtrated high efficiency and reliable performance for the sensors.
