Design and development of an IoT-based Smart Waste Management System.
The Smart Waste Management System is designed to optimize waste collection by notifying authorities when waste bins are full. This system helps keep cities clean by monitoring the fill levels of bins using ultrasonic sensors. It enables efficient scheduling of waste collection, reducing overflow and ensuring better resource management. The project provides an innovative solution for urban waste management as part of smart city initiatives.
The system uses a NodeMCU microcontroller integrated with an ultrasonic sensor (HC-SR04) to monitor the fill levels of waste bins. The ESP8266 Wi-Fi module connects the system to the internet and uploads real-time data to the Blynk IoT platform. When a bin is full, the system sends an alert to the respective authorities or waste management team, ensuring timely waste collection. This IoT-enabled solution minimizes manual monitoring efforts and supports cleaner urban environments.
The ultrasonic sensor measures the fill level of the waste bin by calculating the distance to the waste surface. This data is processed by the NodeMCU microcontroller and transmitted to the Blynk IoT platform via the ESP8266 Wi-Fi module. When the fill level reaches a predefined threshold, the system generates an alert, prompting authorities to schedule waste collection. The system is powered by a 9v DC power supply, making it portable and efficient.
