Design and Analysis of Trash Monitoring System Prototype Based On Internet of Things (IoT) Using MQTT Protocol

Abstrak

On this research, Internet of Things (IoT) as an advanced technology is used to monitor the height of trash from a trash can in order to give notification whether the height of trash is already reaching the maximum height limit or not. To support those needs, we used NodeMCU as a microcontroller, ultrasonic sensor, MQTT as IoT protocol, and Android to display the data. After we did the system performance test, we had the biggest result of end-to-end delay which was 2.06875 seconds when the packet delivery was set to 1000 ms with 3 active nodes and the smallest result of end-to-end delay which was 0.26055 seconds when the packet delivery was set to 100 ms with 1 active node. The biggest result of throughput was 597.17 Bytes/s when the packet delivery was set to 100 ms with 1 active node and the smallest result of throughput was 75.86 Bytes/s when the packet delivery was set to 1000 ms with 3 active nodes. The biggest result of availability and reliability was 99.905% when the packet delivery was set to 1000 ms and the smallest result was 99.833% when the packet delivery was set to 100 ms.
