1.4 MEASUREMENT OF SUNSHINE DURATION
For measurement of sunshine duration, connect the power supply input and
the sunshine duration output. If the direct radiation level is higher than 120
W/m² by definition the time should be added to the sunshine duration. The
output voltage is 1 V. When the sun is not shining the output is 0V.
The usual procedure is to integrate the period with high output, and to store
either the 1 minute values or the totals for each day.
