DEVELOPMENT OF GREEN TECHNOLOGY COFFEE MAKER USING ARDUINO MEGA WITH GOOGLE INTERFACE IOT, LCD TOUCHSCREEN MONITORING, ULTRASONIC SENSOR AND ATS POWER SUPPLY BACK UP

Abstract

This study presents the development of a green technology coffee maker that integrates Arduino Mega, an LCD touchscreen interface, an ultrasonic sensor, and an Automatic Transfer Switch (ATS) for uninterrupted power supply. The system incorporates the Google Interface for Internet of Things (IoT) connectivity, allowing remote monitoring and control. Designed to promote energy efficiency and automation, the system supports sustainable living through intelligent resource management and eco-friendly operations. The researchers utilized Arduino Mega as the primary microcontroller to manage component operations and data processing. The ultrasonic sensor monitors the water level and sends real-time data to the Arduino unit. An LCD touchscreen is installed to enable user interaction by allowing brewing settings and status viewing. IoT connectivity is established via the Google Interface, enabling remote system control and monitoring through the internet. The ATS provides backup power support by automatically switching the system to an alternative source during outages, ensuring operational continuity and energy-efficient brewing. The prototype coffee maker performed as intended. The LCD touchscreen successfully displayed real-time data and allowed user configuration. The ultrasonic sensor accurately monitored water levels, while the system maintained remote access through Google IoT with effective status updates and controls. The ATS functioned reliably, switching to backup power during interruptions without affecting operations. Overall, the system achieved smart automation, energy efficiency, and enhanced user convenience in line with green technology objectives. The integration of Arduino Mega with IoT and sensor technology effectively automated the coffee brewing process and supported real-time monitoring. The touchscreen interface improved user interaction, while the ultrasonic sensor promoted efficient water usage. The use of Google IoT facilitated remote control and system flexibility. Additionally, the ATS ensured consistent functionality during power interruptions, enhancing system reliability. This project demonstrates how smart, energy-efficient systems can contribute to environmentally sustainable practices in everyday appliances.
