I want to classify my data from 3 sensors with arduino so that every time i enter the specific date or hour, or also it can be a period of time like 10 days ago, it shows me the exact data. In other word i want to classify my data so that whenever i want every detail of data, i would be able to get it by entering the information of year,date,time. I also didn't want my data to be in separate files and time stamps. I want to be able to do that within one file and search inside that file...
