Abstract
Penelitian ini menggunakan sensor temperatur LM35DZ sebanyak delapan buah dan menggunakan heater pada temperatur konstan 52.3oC. Output dari penelitian ini adalah temperatur, selisih temperatur, Analog Digital to Converter (ADC), selisih ADC, tegangan dan selisih tegangan. Semakin besar sudut kran yang digunakan, maka selisih temperatur yang dihasilkan semakin kecil, dan kecepatan aliran fluida semakin besar. Perambatan panas pada aliran fluida lebih cepat daripada kecepatan aliran fluida sehingga menyebabkan selisih temperatur besar. Grafik selisih temperatur 0.89oC, 0.49oC, 0.29oC, dan kecepatan aliran fluida 0.12 m/s, 0.26 m/s, 0.48 m/s menunjukkan data berbanding terbalik. Sistem kontrol penelitian ini adalah Atmega32 dan media penyimpanan data adalah Micro Secure Digital (Micro SD). Kata Kunci: ATMega32, aliran fluida, LM35DZ, micro SD, temperatur. This research has used eight temperature sensors of LM35DZ type and the heater. It has been controlled with a constant temperature at 52.3oC. The output of this research was the temperature, the temperature difference, the Analog Digital to Converter (ADC), response the difference of ADC, response voltage, and voltage difference. The temperature difference has been more high, and velocity flows of fluid has been more slow depend on position of faucet angel. The heat propagation fluid flow is more high than the velocity fluid flows, so it will give the more high temperature difference. The response of temperature difference is inversely to the faucet angle. This research was controled by Atmega32, and media the data was storaged with Micro Secure Digital (Micro SD). Keywords: ATMega32, fluid flow, LM35DZ, micro SD, temperature.
