The purpose of your sensor in this type of application is automation so you won't be needing a switch. But if you really need to just connect one side of bulb to one side of sensor, the other side of sensor is connected to one side of switch, the other side of switch is connected to the one side of battery, and the other side of battery to the other side of bulb. ( whooow... this series connection for short.) Did you see a lamp post at nights, it is automatically lighted by sensor called photoresistor. When light hits this photoresistor, the resistance in the circuit increases thereby giving less current and therefore dim/no light. In the absence of light, resistance decreases which in turn increase the circuit current and therby giving light out. Bulb that you see in flashlights has no polarity but LED like in your cellphone has a polarity. Meaning positive of LED must be connected to positive of battery to lit.

what type of sensor are you refering to? dimmer or auto sensor(turns on light when dark), filament or floursence light? usually they're connected in serial, if its a dimmer you do not need an on off switch, the dimmer is also the switch, if its an auto sensor you also do not need a switch as it will turn on the light if it is dark, be careful do not use a normal dimmer for your floursence light, use those for 'floursence'

Get an infrared transmitter/receiver kit. Have the receiver drive a solid state relay which will power your light, or whatever other appliance you would like to power. Good luck.
