Smart Waste Manager revolutionizes airport sanitation by deploying IoT sensors in dustbins to monitor fill levels in real-time, automatically alerting supervisors the moment collection is needed. With this notification, a supervisor can instantly raise and assign a digital task to the nearest waste collection employee, who receives all details directly on their device. Upon arriving at the bin, the employee simply scans its unique QR code with the app, which immediately verifies and records the task's completion with a timestamp, creating a seamless, auditable digital trail from alert to resolution. This end-to-end automated system eliminates manual checks, prevents overflow, optimizes staff routes, and ensures a consistently clean environment through accountable, data-driven management.
