Environmental Monitoring and Smart Garbage Sorting System Based on LoRa Wireless Transmission Technology

Since the industrial revolution, scientific and technological advancements have made life more convenient and have facilitated the rapid growth of the global population. However, the amount of waste produced has also increased. Governments have invested a considerable amount of resources in solving this problem on waste source reduction and recycling. Accordingly, this study with a smart city concept developed a recyclable garbage sorting system that could be used in various locations to help eliminate littering in the city (from inconsistent waste disposal), diminish labor costs, and achieve the goals of increased recycling and reduced waste. This study integrated LoRaWAN communication networks (networks developed using the Internet of Things) with garbage sorting equipment to create a system that offers automated garbage can operation, environmental monitoring, and graphical interface monitoring. The system uses electrostatic capacitance-type proximity sensors to determine the types of garbage deposited in garbage cans. Furthermore, it contains an embedded motor and smart devices that can perform functions such as automatically opening and closing insertion points, sorting waste materials, initiating automated garbage compression, monitoring water levels, and issuing warnings when the water level exceeds the specified limit. This system employs a C# graphical monitoring interface to remind users to remove the garbage.
