Design and Implementation of an IoT-Enabled Web-Controlled Smart Geyser for Energy Optimization and Intelligent Automation

Abstract

The Web-Controlled IoT-Based Smart Geyser is an innovative ESP32-based smart water heating system designed to provide enhanced safety, convenience, and energy efficiency. This system integrates adaptive temperature control, IoT connectivity, and a gas leakage detection mechanism to offer a comprehensive smart home solution. The geyser utilizes ds18b20 waterproof temperature sensor to monitor water temperature with precision. The ESP32 microcontroller processes the analog signals from the sensor and converts them into digital data for seamless integration. The current and desired temperature readings are displayed on a 16x2 LCD screen, ensuring real-time user feedback. Users can set and adjust the desired temperature upto 125°C using an intuitive external PCB-mounted push-button interface. The microcontroller intelligently manages the heating element to maintain the desired temperature efficiently. Additionally, the system incorporates a gas sensor to detect the presence of harmful gases. In case of gas leakage, the system activates a buzzer to alert nearby individuals and simultaneously updates the status on the IoT platform. With IoT integration, users can remotely monitor and control the geyser through a mobile application, enabling enhanced convenience and energy savings. The mobile app also provides real-time updates and alerts, ensuring safety and control at all times. This versatile and compact design is suitable for a wide range of applications, including residential water heaters, industrial heating systems, and other smart appliances. The Web-Controlled IoT-Based Smart Geyser redefines safety, energy efficiency, and user experience, making it an essential addition to modern households and industries.
