based on the PID algorithm, specifically designed for electric kettles. Their work highlights how properly tuned PID controllers can maintain precise temperature levels, improving user safety while also minimizing overheating and excess energy usage.
In today’s fast-moving modern world, traveling has become an integral part of everyone’s life. Hot water is a necessity for travellers, whether for preparing tea or coffee, making instant food, addressing health-related needs or maintaining basic hygiene. However, obtaining hot water, especially in public transportation such as buses and trains can be challenging. To address this issue we are introducing our product ”Thermobottle”. It is a portable, travel-friendly kettle that also functions as a flask, capable of both heating water and retaining its temperature for an extended duration. Unlike a conventional kettle, it features enhanced insulation to improve heat retention. It is designed with an advanced heating coil for rapid water heating, a temperature sensor for real-time monitoring and also a controller to set the desired temperature based on a relay-based automatic shut-off and a buzzer for safety and alert. One of the key advantages of our product is its userfriendly design and compatibility with power sources in public transport systems including 110v ac power in buses and trains as well as standard 230v ac household outlets. This makes it ideal for daily travellers such as office travellers, students,
In a related study, Aisuwarya and Hidayati [2] apply the Ziegler-Nichols tuning method for a hot-water dispenser. Their results show how strategic PID tuning can improve system responsiveness and temperature accuracy—an approach that can be extended to kettle designs. Beyond control systems, the materials and environmental footprint of kettles are also drawing attention. The Design Life-Cycle platform [3] provides an analysis of the material composition and life-cycle impact of electric kettles. It emphasizes the need for sustainable materials and responsible disposal practices to reduce long-term environmental damage. Understanding insulation and heat retention is essential when designing kettles meant for travel or prolonged thermal storage. Anyanwu et al. [4] investigate how vacuum flasks retain heat, offering useful insights into thermal insulation materials and their effectiveness—knowledge that can inform kettle designs meant to keep water hot for extended periods. Meanwhile, Chowdhury et al. [5] introduce a temperature sensitive voltage regulator using RTD sensors for AC loads, which helps in monitoring temperature and adjusting power delivery accordingly. Such systems can support safer,
