Abstract: The three Rís of the environment, Reduce, Reuse, and Recycle the solid waste, generates significant environmental, economic and health benefits. This work proposes a novel intelligent domestic garbage bin for recyclable materials collection and monitoring, based on the Internet of Things (IoT). IoT refers to the networked interconnection of everyday objects, which are equipped with intelligence. The suggested integrated system uses the intelligence of an Arduino microcontroller and two sensors, and creates the IoT Hub by sending the measurements of the sensors to a remote database. The system manages automatically and on-line the garbage bin, providing information regarding the weight and waste level via a friendly web interface. The web page gathers statistics and rewards, informs and warns the users depending on the amount of recyclables that they have collected in a certain time range.

Keywords: Arduino microcontroller, load cell sensor, ultrasonic sensor, SQL database, Internet of Things (IoT), recyclable waste management
