Improper disposal of solid waste that impacts human health and pollutes the environment, arising a need for successful and necessary collection of waste materials. However, most trash bins placed in cities can be seen overflowing due to traditional or inefficient waste management approaches. Therefore, a real-time remote monitoring system is needed to alert the level of garbage in bins to the relevant authority for immediate waste clearance. This paper presents the development and validation of a self-powered, simple connect, IoT solution to monitor the unfilled level of trash bins from a central monitoring station. The end sensor nodes of the developed IoT system are called Bin Level Monitoring Unit (BLMU) which are installed in every trash bin where the unfilled level needs to be monitored. Every BLMU measures the unfilled level of the trash bins and transmits it to a wireless access point unit (WAPU). Each WAPU receives the unfilled level data from several BLMUs and uploads it to the central server for storage and analysis. The waste collection authority can view and analyze the unfilled level of each bin using a smart graphical user interface. The following important experiments were carried out to validate the developed system: (1) the developed bin level monitoring system was tested by filling a trash bin with solid waste at various levels, and the corresponding unfilled level of the trash bin was monitored using the smart graphical user interface. (2) The life expectancy of the BLMU was evaluated as approximately 434 days. (3) The maximum transmission distance between a BLMU and a WAPU is 119 m. (4) The cost of a developed trash bin is 107 USD. Based on the results achieved, the developed trash bins can be suitable for smart cities.

固体废物处置不当会影响人体健康并污染环境，因此需要成功，必要地收集废物。但是，由于传统的或效率低下的废物管理方法，大多数放置在城市中的垃圾箱会被视为溢出。因此，需要一个实时的远程监控系统，以将垃圾箱中的垃圾水平提醒相关部门，以立即清除垃圾。本文介绍了一种自供电，简单连接的IoT解决方案的开发和验证，该解决方案可从中央监控站监控垃圾箱中未装满的垃圾箱。所开发的物联网系统的末端传感器节点称为箱位监控单元（BLMU），该单元安装在每个垃圾桶中，需要监控未填充的位。每个BLMU都会测量垃圾箱中未装满的垃圾并将其发送到无线接入点单元（WAPU）。每个WAPU都从多个BLMU接收未填写的级别数据，并将其上载到中央服务器以进行存储和分析。废物收集机构可以使用智能图形用户界面查看和分析每个垃圾箱中的未填充量。进行了以下重要实验，以验证所开发的系统：（1）通过向垃圾桶中各个级别的固体废物填充来测试已开发的垃圾桶水平监控系统，并使用智能设备监控相应的垃圾桶未填充水平。图形用户界面。（2）BLMU的预期寿命约为434天。（3）BLMU和WAPU之间的最大传输距离为119 m。（4）已开发的垃圾桶的成本为107美元。根据取得的成果，开发的垃圾桶可以适用于智慧城市。
