Smart Bin Enhancing Hygiene and Waste Management with IoT-Based Garbage Gas Detection

Abstract

This project proposes designing and implementing an intelligent waste bin management system in order to increase the efficacy of waste management and enhance environmental sustainability. To monitor and control the environmental conditions near the trash can, the system connects an Arduino Mega microcontroller to a number of sensors and communication modules. The first component of the system is two ultrasonic sensors that provide real-time data on the bin's fill level. Two sensors are placed within the bin to automatically open and close the lids: one gauges the bin's capacity at the moment, and the other regulates the lid. The system contains a MQ2 sensor to detect hazardous gases inside the bin in addition to bin level monitoring, assuring the security of waste disposal and avoiding any concerns posed by offensive odors. A MQ135 gas sensor is also installed to monitor the general air quality around the bin in order to improve waste management practises and create a healthier atmosphere. To ensure proper garbage disposal and prevent littering, an infrared (IR) sensor is utilised to check if any trash has been placed outside the trash can. This feature promotes ethical garbage disposal practises and keeps the neighbourhood tidy.The system also includes a NodeMCU module, which makes it simpler to transfer sensor data wirelessly to a web server. Waste management authorities or other necessary professionals can remotely access this data to check bin levels, air quality, and gas concentrations. For enhanced alert capabilities, the system has a GSM module installed. The waste management staff can be alerted by SMS when bins are overflowing, gas levels are high or the air quality is poor by using this module. This proactive strategy helps in solving potential issues promptly and enables efficient garbage collection and treatment procedures. Last but not least, a buzzer is employed to notify users and bystanders as necessary. Data about the air quality, gas values, and bin fill level are also displayed on an LCD display. Users are provided the knowledge they need to properly dispose of waste, and environmental stewardship is promoted. In conclusion, the proposed interface of an Arduino Mega with ultrasonic sensors, MQ2 and MQ135 gas sensors, an IR sensor, Node MCU, GSM module, buzzer and LCD produces an intelligent trash bin management system that offers monitoring, remote data access and alarms. This technology will transform waste management practices, increase environmental awareness, and make cities cleaner and healthier.
