'CR1000X Series Datalogger
'Example datalogger program for Apogee Instruments SU-202/205 ultraviolet sensors

'Wiring:
'White -> Single ended chanel 1 (analog in)
'Black -> Ground (Signal and power ground)
'Red -> Power (5 - 24 VDC)
'Clear -> Ground (Shield)
'Note for non-Campbell Scientific systems:  If the power supply ground is not shared with the signal ground on the datalogger, a bridge wire connecting the two grounds will be needed. 

'Explanation of Constants and Variables Used in Datalogger Program
'BattV = datalogger battery voltage
'PanelT = datalogger panel temperature
'UV = incoming global ultraviolet (UV) radiation in umol m-2 s-1 (micromoles per square meter per second)

'Declare Public Variables
Public BattV, PanelT
Public UV, OutputmV

Const CalFac = 0.4 '(Watts per square meter)  Change this value to match your sensor model, and/or desired units of measurements
