Development of internet of things (iot) based waste management system

In response to the global challenge of improper waste disposal and solid waste management an Internet of Things (IoT)-based waste management system was developed to address the challenge of inappropriate garbage disposal. Three systems were designed using ultrasonic sensors connected to NodeMCU to measure garbage levels in bins. Data was transmitted to an online database via Firebase and an Android app was developed to display real-time information on a Google Map. Bins exceeding 70% capacity were highlighted in red color and green color otherwise. The system provided efficient, real-time waste management, allowing users to access information remotely, locate nearby bins, and contribute to improved cleanliness and sanitation in urban areas.
