Automatic Waste Management based on IoT using a Wireless Sensor Network

Abstract

Improper waste disposal causes hazard to human health and environmental pollution while causing a desire for a successful and significant series of waste materials. However, due to outdated or ineffective waste management techniques, most garbage cans placed in towns may be seen to be overflowing. Therefore, a real-time remote tracking device is required to inform the appropriate authority of the volume of trash in boxes so that it can be immediately cleared. The enhancement and evaluation of an IoT self-powered, simple-to-connect alternative to monitor the level of overflowing trash cans from a valued tracking station are provided in this work. Bin Level Monitoring Units (BLMU), the last sensor nodes of the developed IoT device, can be installed in each garbage can where the unfilled stage is desired to be observed. Every BLMU measures how empty each trash can is and communicates that information to a wi-fi access point unit (WAPU). Each local device is connected to a central Internet of Things device that is installed in each region using LoRa devices, which offer longer communication distances. This facilitates the connection of several devices to a network and allows accessibility to the IoT module. Consequently, this technique makes it simpler to keep an eye on the garbage can in real time.
