Automatic BIN Using 800 L SIM Module

Abstract

The increase in the volume of waste in urban areas due to population growth and community activities demands smart solutions in waste management. This research aims to design and implement an automatic trash can system based on Arduino Uno microcontroller equipped with a GSM communication module SIM800L to improve the efficiency and responsiveness of waste management. The system utilizes two ultrasonic sensors: one to detect the presence of the user in front of the bin so that the lid opens automatically without touch, and another to monitor the capacity of the bin in real-time. When the bin is fully detected, the system sends a notification in the form of an SMS message to the janitor and turns on the red LED indicator; The green LED lights up during normal conditions. The test results showed that the system worked reliably with a detection accuracy rate of >95% and a success rate of SMS delivery of 100% in strong signal areas. The main advantage of this system is its ability to operate autonomously, energy-efficient, and compatible with GSM infrastructure without dependence on Wi-Fi or dedicated applications. This design is expected to make a real contribution in supporting smart city programs, especially in adaptive waste management and based on the Internet of Things (IoT).
