This a simple Arduino-based data logger. The systems monitors any change of state of a digital pin (here #2) of the Arduino, and writes the time and date of each change to the SD card (file "data.txt" ...

A data logger is a tool which monitors physical data such as voltage, current, power, ... and stores that information somewhere. It can have a display, a storage space, anything useful to treat data.

Here is the Arduino Data Logger Project covered with circuit diagram and code to learn how we can log temperature and humidity to SD card at a specific interval of time. Arduino Data Logger Project ...

Once the data is logged, the SD card can be removed and the .csv file opened in spreadsheet software to make a graph showing temperature change over time. Posted in Arduino Hacks , green hacks ...

Because the logging data applications are external and on-demand, the serial source application may also include a ‘data taken’ time tag in its saved transmission. Any serial link connected into the ...

Since the RTC has kept the current time, there is enough information to display the duration of the blackout. ... Logging data with an Arduino is old-hat for most Hackaday readers.

With this sensor, acceleration data can get collected and analyzed. There are a large number of people using the road every day, thus the road profile should be concerned. The aim of this thesis is to ...
