Abstract
Water heaters are widely used in homes, hostels, hospitals, and industries, but they often lead to energy wastage and safety issues when left ON unnecessarily.
This paper presents a Smart Auto-Off Water Heater System using ESP32 that automatically controls water heating and usage.
The system monitors water temperature, usage count, and object detection to prevent unnecessary water flow and power consumption.
A mobile application (Blynk) and OLED display provide real-time monitoring and control.
The proposed system improves energy efficiency, safety, and smart water management.
