Waste Monitoring System based on Internet-of-Thing (IoT)

Abstract

Currently, most of waste management system is implemented using a conventional system. The organisation such as Alam Flora Sdn. Bhd manages the domestic waste by assigning the worker to collect the waste without identification system. This paper presents a development of waste monitoring and collecting system based on Internet-of-Thing (IoT). The hardware implementation for the system consist of NodeMCU (microcontroller board) connected to two ultrasonic sensors with Wifi module (ISM Band 900) attached to the board. In the system, these sensors are utilised to implement an automatic lid opener and to update the waste level condition for monitoring system. The developed system is designed to monitor the waste level (condition) in the bin (‘full bin’ or ‘not full’) via internet through mobile application (Apps). The developed Apps provides a real-time update of the waste level status for collection. The real-time update from the sensor is uploaded through the developed mobile Apps via URL to the database. Waste collector or end user need to access the update via mobile Apps for further action. In this project, the ultrasonic sensor sensitivity is tested on ‘flat’ and ‘non-flat’ waste type. The result showed that type of waste (‘flat’ or ‘non-flat’) with specific angle of reflection has influenced the sensor sensitivity to identify the waste level status. The developed system could be potentially utilised to improvise the conventional system waste collection to more effective system.
