Automation of Waste Segregation Via Sensors by Using PLC

Abstract

With the growing population rate, the amount of waste being produced is also increasing at a very fast rate. These days in our environment waste management is one of the major problems, the best solution has been proposed to solve this problem is segregating this waste and recycle it. But segregating it manually is complex, dangerous and utilizes more human efforts, cost and time. The proposed system designed to separate five types of wastes into respective bins automatically by the sensing of different sensors (capacitive, inductive, proximity and photoelectric sensors) to detect any object which is moving on a conveyor belt with the help of hydraulic cylinders. The programmable logic controller (PLC) used as main component and proposed system is simulated using Siemens Semitic S7-200 simulator and the results show that the system has been programmed successfully.
