Abstract

one Adafruit MCP9808 sensor and five Adafruit MAX31856 thermocouple amplifiers. The design of this data logger allows temperature measurement in various applications, with a focus on monitoring room temperature. The prototype can be used in experiments, research, and industrial applications that require accurate temperature monitoring. This temperature data logger has the potential for wide-ranging applications in various contexts, with advantages in flexibility and affordability. The research validates that the MCP9808 sensor and MAX31856 amplifiers have a high level of accuracy in temperature measurements. The results of temperature measurements in a room environment indicated a temperature of approximately 29 ℃. This data logger design serves as a robust alternative for researchers who face limitations in acquiring standard commercial data loggers. The prototype has the potential to be a valuable tool in experiments and scientific research in various applications that demand precise temperature monitoring.

Abstract

Pengukuran suhu memegang peranan krusial dalam berbagai aplikasi, dari penelitian ilmiah hingga industri. Dalam upaya untuk memastikan akurasi pembacaan suhu, amplifier thermocouple, seperti Adafruit MAX31856, seringkali digunakan. Penelitian ini bertujuan untuk menyelidiki dan menganalisis hasil pembacaan dari amplifier thermocouple Adafruit MAX31856, yang merujuk pada termokopel tipe K yang umum digunakan dalam pengukuran suhu tinggi. Metode analisis regresi linier sederhana digunakan untuk memahami tingkat kesamaan pembacaan dari sepuluh amplifier TC1 hingga TC10 terhadap hasil pembacaan termokopel tipe K. Analisis ini dilakukan dengan bantuan aplikasi MS Office Excel, dan hasilnya sangat menarik. Hasil analisis mengungkapkan bahwa nilai koefisien determinasi (R²) berkisar antara 0,9999 hingga 1, menunjukkan tingkat kesamaan yang sangat tinggi dalam pembacaan amplifier tersebut. Hal ini mengindikasikan konsistensi dan stabilitas pembacaan suhu termokopel tipe K yang dihasilkan oleh amplifier thermocouple Adafruit MAX31856.
