Smart, Safety, Advanced TechnologyAbstract
Traditional water heaters often rely on manual temperature control, which may lead to overheating, energy wastage, and potential safety hazards. To overcome these limitations, efficient and automated temperature monitoring systems are required to ensure safe and optimized water heating. This project focuses on the design and implementation of an intelligent water heating system that monitors and controls water temperature in real time. The proposed system is built using an Arduino Uno microcontroller and a waterproof temperature sensor to continuously measure the temperature of water inside the heater. The temperature sensor collects real-time data and sends it to the microcontroller for processing and analysis. Based on the measured temperature values, the microcontroller automatically controls the heater using a relay module to maintain the desired temperature range. When the water temperature exceeds the predefined limit, the relay switches off the heater to prevent overheating. Similarly, when the temperature falls below the set threshold, the system activates the heater to maintain the required temperature. This automated approach improves safety, energy efficiency, and user convenience compared to conventional water heating systems. The integration of microcontroller-based control and real-time monitoring ensures optimal heating performance while reducing human intervention. The proposed system demonstrates the potential for developing smart and energy-efficient water heating solutions suitable for residential and industrial applications
