Automatic Waste Segregator using Arduino Uno with Wet, Metal, and IR Sensors

Waste management is an optimal problem in most cities because of the rapidly growing population and inadequate waste disposal techniques. Poor waste segregation causes a large percentage of wastes7 to go to landfills, along with pollution and even more significant problems regarding recycling. This research develops an automatic waste segregator with Arduino Uno microcontroller using wet, metal, and infrared (IR) sensors to differentiate wastes as wet, dry, and metal. The system can detect the properties of various types of waste materials, and segregates them into appropriate bins, which increases the efficiency of waste sorting and minimizes environmental problems. This proposed design intends to reduce manual effort, improve the recycling percentage, and aid in smart waste management. It is designed to be low cost, of a reasonable size, and can be used in residential, commercial, and industrial places. It is green in nature because it uses embedded systems and sensors for automated waste classification, which can further incorporate IoT and artificial intelligence for a greener approach. In this manner, the waste disposal process can become fully automated, minimizing health risks and promoting sustainable urbanization.
