Understanding IoT-Based Energy Solutions for Hostel Environments

Abstract

With the rapid rise in energy consumption and the need for efficient resource utilization, smart energy monitoring systems have emerged as a promising solution. This survey paper reviews existing literature on IoT-based smart energy monitoring and billing systems, particularly focused on hostel or institutional environments. Traditional energy billing mechanisms lack real-time data visibility and transparency, leading to energy wastage and delayed cost awareness among users. Internet of Things (IoT) technology enables real-time energy tracking through smart sensors, wireless communication, and cloud-based analytics.

This survey discusses various architectures, communication protocols (such as MQTT, Wi-Fi, Zig- Bee, LoRaWAN), microcontrollers (like NodeMCU, ESP32, Raspberry Pi), and visualization techniques used in modern smart energy systems. Furthermore, it explores automated billing models, mobile/web- based dashboards, predictive energy analysis, anomaly detection, and integration with renewable energy sources.

Real-world case studies demonstrate practical benefits, such as 10-20% reduction in hostel elec- tricity consumption within 6 months of implementation. The paper concludes with research gaps and future directions towards achieving energy-efficient, scalable, and user-centric hostel energy management systems.
