This paper introduces ADIMS (Adaptive Distributed Infrastructure Monitoring System), a cloud-based telemetry platform that facilitates real-time monitoring and management of distributed field infrastructure across various organizational contexts. ADIMS solves the complex problem of integrating diverse devices by supporting multiple communication protocols, including TCP/IP, MODBUS, LoRaWAN, Sigfox, and LTE. This makes it easy to get data from third-party sensors and equipment. The system architecture has three main layers: a field acquisition layer that supports multi-protocol communication, a cloud-based processing and analytics engine, and a customizable dashboard framework that gives operational and managerial insights. We show that ADIMS could be used in smart city infrastructure by looking at similar systems and finding that they could use 15–30% less energy and save 25–35% on predictive maintenance costs. The platform’s protocol-agnostic design makes it easy to set up quickly at universities, NGOs, government buildings, and industrial sites. This helps achieve sustainable resource management and climate action goals that align with the UN Sustainable Development Goals.
