This function calculates the daily percentage of DC signal
recorded by the pm25_A
, pm25_B
, humidity
, and
temperature
channels. The data are flagged as DC signal when the
standard deviation of an hour of data from each channel equals zero.
The number of hours with a DC signal are summed over the day and a daily DC
percentage for each channel is returned.
