Rancang bangun data logger berbasis Arduino sebagai penyimpan data

Abstrak

A Data recording system using an Arduino-based multi-channel data logger has been designed. This data logger can be installed in any measuring instrument that requires data recording. The data logger comprises a 74HC4051 multiplexer module that has eight inputs for developing input lines on the Arduino. Every signal that enters the multiplexer module will be sent to Arduino Uno for calculations and channel sorting. Each calculation data is stored on a storage module in the form of a microSD. The system is tested by using voltage variations on each channel. Based on the test results, the multiplexer can properly channel every signal they receive without path errors. The storage module can also store every data received by the Arduino Uno with a storage interval of every second. The multiplexer has a 100% accuracy rate for line sorting. The storage module as a data logger also has an accuracy of 100%.
