- In modern urban environments, efficient waste management is a significant challenge. This paper presents the design and implementation of an IoT-based smart trash bin system that integrates ultrasonic sensors, weight sensors (simulated), and artificial intelligence (AI) to optimize waste collection processes. The system utilizes ESP32 microcontrollers and ESP32-CAM modules to monitor the fill levels and types of waste. Ultrasonic sensors measure the distance to the waste surface, while potentiometers simulate the weight of the trash. An AI algorithm processes images captured by the ESP32-CAM to classify the waste, enhancing the accuracy of the monitoring system. Data from the sensors and AI analysis are transmitted via Wi-Fi to a centralized server, where it is stored and visualized using Oracle APEX dashboards. The sensor's software can update its status to "full"based on the weight and level readings; a mobile application developed with MIT App Inventor also allows users to update the status of the trash bins via a mobile device. This enables city waste management authorities to make informed decisions, reducing operational costs and improving environmental sustainability. The proposed system demonstrates significant potential in enhancing urban waste management efficiency through real-time data acquisition, processing, and intelligent decision-making.
