Abstract:
This study aimed to develop an Arduino Uno-based automatic locking system that incorporates RFID authentication, a waste level monitoring system, and SMS alerts to increase the effectiveness of waste collection and optimize school cleaning personnel’s workflow. The researchers used experimental and applied research designs to develop and test the product. The materials used to create the product were the following: an Arduino Uno board, a battery holder, a breadboard, a buck converter, an ultrasonic sensor, jumper wires, a Li-ion battery, an LCD, a servo motor, a SIM800L V2 GSM module, an RFID reader and tag, a brass cup hook, a PVC ceiling panel, a plastic trash bin, and a trash bag. The researchers encoded a program into the components and installed it on the housing. To gather data, the researchers distributed a validated questionnaire to 15 respondents, including 5 janitors and 10 students. They let the respondents try the product to test its performance level in sending SMS, auto-locking the lid, opening the lid using RFID, and its effectiveness. The findings show that the system performed well and effectively reduced waste overflow. Findings reveal that the waste monitoring system significantly assisted the cleaning staff by reducing the need for manual waste monitoring and enhancing overall waste management. To further improve the product, the researchers recommend integrating radio communication for faster response on full trash bins, an automated air purification system for odor control, weatherproof housing materials for the product’s durability, and integrating solar panels for continuous, self-sustained operation.
