The Ambient Light Sensor Is A Photo Sensitive Resistor Housed In A Water Proof Enclosure.
It Is Used In Conjunction With The OE310-21-LP Lighting Controller To Sense The Presence Or Absence
Of Ambient Light For The Control Of Lighting Circuits Connected To The Controller. The Sensor
Has A Resistance In Excess Of 1M Ohms In Darkness And Ranges Down To Less Than 1.5 K Ohms In
Bright Light. The Sensor Wire Connections Are Non-Polarized. See The OE310-21-LP Wiring Diagram For
Correct Wiring Connections. See Note 1 For Mounting Location Cautions.
