Abstract: To improve environmental sustainability, this paper presents an intelligent IoT-based smart waste management system that streamlines the waste sorting procedure and provides real-time monitoring. Using a Node MCU microcontroller and moisture, ultrasonic, and conductivity sensors, the system uses a decision-based algorithm to accurately sort waste into three categories: wet, dry, and metallic. A cloud-based analytics platform receives real-time data from ultrasonic sensors that continuously measure the bins' fill level. Using a data transmission algorithm, the system automatically notifies users via SMS or Telegram when the fill level reaches a preset level, enabling timely waste collection and avoiding overflow.
