Abstract
Waste management has always been an important topic of studies. One of the efforts to handle waste in the Era of Industrial Revolution 4.0 was to start by designing a smart bin. The purpose of this study is to design an integrated monitoring system of several IoT-based smart bins. The hardware and software components used in system design were Wemos D1 Mini Pro Microcontroller, HC-SR04 ultrasonic sensor, DHT22 temperature-humidity sensor, Blynk and Arduino IDE. Blynk was used in building an integrated monitoring system for several garbage bins. In this study two samples were monitored through the Blynk application. The height value of the garbage was measured by an ultrasonic sensor while the humidity and temperature values were measured by the DHT22 sensor. In realtime, every measurement results of rubbish height, temperature and humidity were displayed by the Virtual Level of Blynk application on the smartphone. Graphical measurement results could also be displayed on Blynk.
