BurstData collection time: what interval gives the best data #19

Open USGSminc opened 5 years ago

We are trying to determine the best burst sampling rate for our water quality sensors. Currently we are taking 30 samples, taken one second apart, determining the median, and reporting this value. We are looking into creating a function of the program that will let us take all thirty samples and subsection within this array to see how different length samples or rates impact the quality of the reported data. For instance, taking an instant reading, vs 5 one second intervals, vs 10 vs 15 etc. Other combinations playing with interval between samples are possible too. We need to report each sample interval type simultaneously with other types in order to directly compare them. Currently, after the single average is created, the array is flushed so it is available to be used at the next scan. Learning how to take the array that is stored internally and how to manipulate it in a variety of ways is what we need to figure out.
