Abstract

With the increase of population growth around the world, the rubbish generated everyday is getting more and more until it reaches an alarming stage. This will not only affect the cleanliness and sustainablity of the environment, but also endanger the health status of people around theworld. With the advancement of technology, almost everything can be IoT based. In order to preserve the environment and enhance humans’ health, smart waste management system and recycling is getting more attention. This project proposed a system that can segregate metal and non-metal waste automatically with IoT features. The system will detect and categorized waste into metal and non-metal, making the waste segregation and recycling more efficient. First, this system utilized Arduino Uno R3 as microcontroller together with a ESP-01(S) WiFi module to enable the processing of sensor data, controlling the system, and allowing remote monitoring of waste level in the dustbin via IoT capabilities. Ultrasonic sensors, IR sensor and inductive proximity sensor are used to identify different waste materials; while servo motor serves as an output to help segregate the waste into metal or non-metal bin. The sensor data are uploaded to Blynk Cloud and then send to the Blynk IoT app for remote-monitoring purpose.
