Measuring thermal conductivity of a jute-based product is an important aspect to choose the best product to fit for right purpose. For this reason, it is important to measure thermal conductivity with accuracy. In the existing thermal conductivity machine of Physics Department, temperature is measured with analog thermometer. Reading analog thermometer is not precise and accurate enough. Therefore, it is important to measure temperature reading more accurately, that means digitally. Temperature sensor DB18B20, Arduino Nano and a display unit were used to show the temperature digitally. Thermal conductivity of PP, Jute-PP composite, Jute-Polyester composite, and Jute-Wool composite samples was measured both conventionally and digitally. For both conventional and digital approaches, the thermal conductivity values of the samples mentioned above differed by 0.04%, 2.84%, 6.01%, and 5.54%. Considering the heating rate, there is an observable trend: a decrease in specimen width correlates with an increase in heating rate. Additionally, specimens with the same width show varying heating rates depending on the material composition.
