Design and Implementation of an Automated Odor-Controlled Smart Waste Bin with Real-Time Monitoring Using Arduino Nano

The purpose of this paper was to describe the design and implementation of a low-cost, automated smart waste bin that uses sensors to monitor and improve both the cleanliness of homes and the environment in real-time. It also has the function of providing an effective, hands-off method of disposing of trash and automatically removing odors from the environment. The primary components of the system are the Arduino Nano microcontroller and the multi-modal sensor array connected to it. The Arduino Nano allows users to have a low-cost option for controlling how their smart trash can works. The ultrasonic proximity sensor enables touchless access to the smart trash can. In addition, the internal ultrasonic waste sensor continuously monitors the amount of waste in the can so that users can know when it needs to be emptied. The VOCs detected by the internal odor sensor will trigger the high-velocity blower fan to blow the bad smells out of the smart trash can using the IRFZ44N MOSFET driver. Users receive feedback from the HMI (Human-Machine Interface), which includes the I2C-enabled LCD display and the "Traffic Light" LED indicator system, about whether or not the air quality is good or bad and if the smart trash can needs to be emptied. Experimental testing showed that the system can respond appropriately to maintain a clean home environment by using its various automated functions and air purification functions.
