Abstract
The article discusses IoT based solutions to improve waste collection and monitoring in public waste containers. The paper examines whether the monitoring system used in the measurement process can be used to monitor the filling of containers. The system consists of a wireless module connected to an ultrasonic sensor. The data sent makes it possible to calculate the empty space in the waste containers. The values are obtained by measuring the distance from the top of the container to the surface of the waste. Low-power long-distance broadband network (LoRaWAN) transmitters were used for data transmission. The aim of the research: to test an inexpensive monitoring system and to describe a new system of sensors and transmitter modules. The system is characterized by extremely low power consumption and a wide range of sensors used. Measurements were performed in Vilnius. Containers of two types of sizes were analyzed, measurements were performed at five points of horizontal cross section of the containers. The study was performed at two different levels of container filling. The results show that an ultrasonic sensor can representatively measure waste filling depths at different levels of container filling. Based on the results, this sensor can be recommended in the intelligent waste management market. Such a system can provide the necessary data for optimizing waste collection processes in cities and avoid container overcrowding problems.

Summary
ATLIEKŲ KONTEINERIŲ UŽPILDYMO LYGIO MATAVIMAS NAUDOJANT DAIKTŲ INTERNETO IR „LORAWAN“ TECHNOLOGIJOS MAŽOS GALIOS JUTIKLIUS. Vertės gaunamos matuojant atstumą nuo konteinerio viršaus iki atliekų paviršiaus. Atliekų tvarkymas miestuose naudojant „LoRaWAN“ technologiją ir mažo galingumo daiktų interneto modulių ir jutiklių sistema yra visiškai originalus ir šiuolaikiškas sprendimas. Naudojama novatoriška IoT mazgo architektūra atliekų konteinerių užpildymo stebėsenai. Atliekų konteinerių užpildymo lygio matavimas naudojant daiktų interneto ir „LoRaWAN“. Matavimai atlikti penkiuose konteinerio horizontalaus pjūvio taškuose, dviejų dydžių konteineriuose su dviem atliekų užpildymo lygiais. Pagrindiniai tyrimo duomenys – atstumas nuo konteinerio viršutinio horizontalaus paviršiaus iki atliekų paviršaus:.
