Question from Mr. suroto munahar 2020.11.18 13:36:55 my name is Suroto Munahar. Research concentration in mechanical engineering. I am very interested in the research of Mr. Agus Ulinuha. On this occasion I would like to ask what is the ability of the sampling rate to retrieve data from your research.

Reply from Dr. Agus Ulinuha 2020.11.18 14:21:43 Thank you Mr. Suroto for your good question. I am trying to understand your question and hopefully I can get what exactly you ask. The measurements are taken by sensors. Some data may directly displayed but some of them requires further process to get useful information to display. The data are continuously measured by sensors and the data/information are recorded and acquired such that some information may be presented. Therefore, real time operating condition of the motorcycle may be presented in TFT display. The data/information are stored in SD card and this is backed-up with separate battery such that the data may not loss even the motorcycle is off. Again thank you for your question.

Reply from Mr. suroto munahar 2020.11.18 14:47:48 In the data acquisition process, there is a variable sample rate taken by the microcontroller. The higher the sample rate, the microcontroller with larger specifications is needed. For the research you did, how much is the microcontroller ability to take samples? (that^s the father I ask) thank you

Reply from Dr. Agus Ulinuha 2020.11.19 14:45:10 Thank you for your further question. The microcontroller that we are using is Arduino Mega 2560. This Arduino uses Atmega Chip 16U2 supplied with 5 Volt and has reading resolution of 10 bit (1203 dec). It therefore needs 100 microseconds (0.0001 s) to read the analog data. On average, it is capable to read 10,000 times per second. It is expected to be sufficient for reading the data at the developed system. Again thank you for your nice question.
