project information

Project Overview

The project is a smart IoT-based Building Management System tailored for small to mid-sized buildings, focused on reducing energy consumption and simplifying facility operations. Built for end-users, administrators, and maintenance teams, it provides real-time monitoring, device control, and performance insights through user-friendly web and mobile interfaces. With features like automated alerts, energy usage analytics, and remote access, this intelligent platform helps streamline building management, optimize energy efficiency, and lower operational costs, making it a vital component of a modern IoT energy management ecosystem.

Challenges Faced by Business

Challenges Faced by Business
Inefficient Energy Management

Inefficient Energy Management

Manual control of lighting and HVAC systems led to inconsistent usage patterns and more energy consumption. Energy-saving opportunities were frequently missed due to a lack of automation or intelligent scheduling.

Lack of Centralized Monitoring and Control

Lack of Centralized Monitoring and Control

The absence of a unified dashboard made it challenging to monitor and manage systems efficiently. Operators relied on fragmented tools, reducing responsiveness and operational clarity.

Limited Remote and Mobile Accessibility

Limited Remote and Mobile Accessibility

The system lacked a mobile-friendly or browser-accessible platform, making it difficult for facility managers to access or control equipment on the go or from remote locations.

Integration and Scalability Challenges

Integration and Scalability Challenges

There was limited capability to manage systems zone-wise or integrate with existing legacy infrastructure, such as LonWorks, restricting flexibility and scalability in building management.

Solutions Provided by DITS

Solutions Provided by DITS

A smart building automation system combining IoT, SCADA, and PWA technology to deliver centralized control, real-time monitoring, and zone-based optimization for enhanced energy efficiency and user convenience.

Unified Smart Control System

Unified Smart Control System

We built a progressive web application (PWA) integrated with IoT and SCADA, enabling centralized control and monitoring of lighting, HVAC, and alarms - all accessible via a browser, with no app installation required.

Real-Time Monitoring and Alerts

Real-Time Monitoring and Alerts

The system provides live data from sensors that track temperature, humidity, motion, and occupancy. A built-in alarm module displays real-time alerts from devices, allows users to view and acknowledge events promptly.

Intelligent Zone-Based Management

Intelligent Zone-Based Management

Users can control lighting and air conditioning in specific areas or rooms using zone-based configuration. This allows granular energy optimization and customized environmental control for different zones.

Advanced Access and Visualization Tools

Advanced Access and Visualization Tools

QR-code-based login simplifies access control by room or zone. Trend visualization features display real-time and historical power usage and system performance, while PWM-based dimming allows precise lighting control beyond basic ON/OFF states.
