Development of Ideal Gas Kit using Pressure and Temperature Sensors via Arduino

Year: 2024

Type: article

Abstract: This study presents the development of a low-cost experimental kit to investigate the ideal gas law using a K-type MAX6675 thermocouple and MPX5700AP pressure sensor interfaced with an Arduino microcontroller.The kit enables real-time measurements and LCD display of pressure and temperature data, making it suitable for classroom demonstration and inquirybased learning.Experiments based on Boyle's law and the combined gas law were conducted, and the data showed a high correlation with theoretical predictions.The calculated error in the gas constant was only 0.08%, and the estimated system volume was 2.03 cc, and also the number of moles of gas was -3 2.30 × 10 moles.Compared with existing commercial kits, the proposed design is more cost-effective, portable, and educationally versatile.The findings support the pedagogical value of using microcontroller-based sensors in physics education.
