Implementation of Smart Building Monitoring Temperature and Humidity Based on IoT Web at PT. MINORI

Abstract

This community service activity aims to address the manual monitoring of temperature and humidity in PT. MINORI's training rooms, which results in slow response times and a lack of historical data. The solution implemented is an Internet of Things (IoT) based environmental monitoring system using an ESP32 microcontroller and DHT22 sensor integrated with a web dashboard for real-time monitoring and data storage. The stages of the activity included a partner needs survey, device design and testing, system installation, and operational and maintenance training for technical staff. The results of the implementation showed that the system achieved 95% data delivery success with an average latency of 2 seconds, as well as a 95% accuracy rate for temperature and humidity measurements compared to the reference device. The outputs of the activity include installed monitoring devices, access to the monitoring dashboard, and operational and maintenance guidelines for the system. This activity has had an impact in the form of increased efficiency in monitoring the training room environment, and is planned to be developed in other training rooms as part of the ongoing implementation of IoT-based smart buildings.
