temperature information. Thermoglow is an innovative temperature indicator leveraging LED technology to provide a visual representation of temperature changes [5,6,7]. This intelligent device offers a user-friendly way to monitor temperature variations in various settings. By employing a range of LED colours and patterns, ThermoGlow offers an intuitive and convenient method for users to assess temperature changes, making it an ideal tool for diverse applications, from home use to industrial settings. Its sleek design and functionality make it a versatile and reliable temperature indicator, catering to the needs of users across different environments The LM35 is a precision integratedcircuit temperature sensor that provides an accurate and linear output directly proportional to the Celsius temperature. It's a popular choice for temperature measurement due to its simplicity, accuracy, and ease of use. The LM35 sensor doesn't require external calibration or trimming and provides temperature readings in the range of -55°C to 150°C. Its straightforward analogue output makes it compatible with most microcontrollers and digital systems, making it widely utilized in various applications such as environmental control systems, industrial automation, medical devices, and automotive applications. Its small form factor, low power consumption, and reliability have made the LM35 a staple in temperature sensing technology [8,9,10]. The significance of LED Temperature indicator lies in its ability to address various practical needs and applications such as:
paper outlines the design and implementation of a temperature indicator using LM35 temperature sensor and LED without the use of Arduino. The LM35 sensor provides an accurate temperature reading, and the LED visually represents the temperature level. This paper covers the paper’s objectives, components, circuit design, and working principle. The paper provides a captivating blend of temperature monitoring, creating an engaging and informative visual display of changing environmental conditions. This innovative circuit employs a thermistor (LM35), to capture real time temperature data. The sensor’s output is then meticulously processed by an integrated circuit (IC) that intricately controls a series of vibrant LEDs. What makes this paper truly enticing is its ability to transform mundane data into a mesmerizing visual spectacle. As temperatures rise or fall, the LEDs gracefully light up or dim, creating a dynamic and eye-catching display. It can be used as a learning tool, or simply a decorative temperature indicator. The “Temperature indicator LED circuit” paper serves as an excellent example of data visualization in a way that is both accessible and visually captivating.

1.2 LITRATURE REVIEW In February 2017, Shekhar Mishra et al in their paper “Temperature Control Based LED indication system” have done an Industrial Temperature Controller using LED, LM35 Temperature Indicator, and ATS952 Microcontroller [11]. They have also used a 89S52 microcontroller brain, temperature sensor LM35 which senses the actual temperature of the system, to convert the temperature recorded by the sensor into a digital quantity, LCD for display and to turn the LED’s on or off.
