(**)
One sample consists of all the quantities measured and calculated by the data logger at the same instant of acquisition. For example,
the model HD35EDW1NTC measures two quantities and calculates five quantities (the derived humidity quantities) and one sample
includes one temperature measure and six humidity measurements (the relative humidity measure plus the five derived quantities).
(***)
The minimum logging interval may be smaller if the data logger only stores some of the available quantities.

CO
measurement is updated every 15 s.
