'Wiring: 
'White -> Single ended channel 1 (Sensor output signal)
'Black -> Ground port (Signal ground)
'Red -> Sensor input power (5 to 24 VDC, 12 VDC recommended if possible)
'Clear -> Ground (Shield)

'Explanation of Constants and Variables Used in Datalogger Program
'BattV = datalogger battery voltage
'PanelT = datalogger panel temperature
'Lux = incoming luminous flux radiation in Lux (lumens per square meter)

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

Const CalFac = 2.0 'Change this value to match the calibration factor of your specific sensor model

'Define Data Tables

	Minimum(1,BattV,IEEE4,0,False)
	Sample(1,PanelT,IEEE4)
	Average(1,Lux,IEEE4,False)
