Abstract
Waste management still faces major challenges, particularly due to the use of conventional bins that mix metal and non-metal waste. This practice leads to the accumulation of mixed waste, negatively impacting environmental cleanliness and aesthetics, while also complicating the recycling process, which is crucial for ecosystem health and sustainability. Therefore, this study aims to design and develop an automatic metal and non-metal waste detection device based on the Internet of Things (IoT), utilizing the ESP32 microcontroller. The system integrates an ultrasonic sensor for detecting non-metal waste and monitoring volume, an inductive proximity sensor for identifying metal waste, and an infrared sensor to indicate when the bin is full. The device successfully classifies waste into two categories: metal and non-metal. The inductive proximity sensor effectively detects metal waste, while the ultrasonic sensor accurately identifies non-metal waste within a range of less than 15 cm. A servo motor directs metal waste to the right and non-metal waste to the left. Detected waste types are displayed on an LCD screen, and notifications are sent via the Blynk application. This system is expected to improve the efficiency and accuracy of waste management and support more effective environmental conservation efforts.
