Abstract
Solid waste management is a serious problem in most developing countries especially Nigeria, where the population is exploding and majority of the population still use open waste dumps that contributes to environmental pollution and degradation. Proper waste management system is very vital for a cleaner and safer environment. In this study, simulation and construction of an automatic trash bin system with mobile wireless technology was carried out using Atmel AT89S51 microcontroller. The circuit was simulated using Proteus ver8.0 via Arduino Uno IDE programming language using embedded C language. The various stages include HC-SR04 ultrasonic sensor, SIM800L GSM modem, microcontroller unit, and regulated power supply unit. The device prototype was constructed on a Vero board and tested for continuity, power ON and validity test for different trash levels. Results shows that, the device can sense the waste level in the bin and then send an SMS to the user when the waste level reaches a certain threshold value to alert the user that the bin is full. The device can be used for effective waste monitoring in homes and commercial areas for proper waste management for a cleaner and healthy environment.
