I am looking for having some sensor based switches which will turn on/off the lights based on the light conditions during the day (i.e. turn on when there is less light and turn off when there is more light)
Also, is there a way to connect this switch with multiple light source?
Please let me know.
Put the sensor in the space you are trying to light, and suddenly this "common need" becomes "not a need at all" which is why you can't find them, since that's how it's done, when done conventionally.
Either move the switch into the room or get a remote sensor switch and put the sensor in the room.
It sounds as if the light is being controlled by a single 3-way switch. The hot lead is run to the common and two switched hots are run to the traveller terminals.
You could create a master switch by adding a single pole switch that interrupts the hot lead before it goes to the 3-way. You could expand the box holding the switch to a 2-gang type and wire the new switch with the existing hot lead and a short pigtail from its second terminal to the 3-way common.
You also could do the same with a double switch in the existing single gang box. Either a single pole/3-way combination or even a 3-way/3-way combination would work.
In this case, the pigtail runs from one terminal of the master switch (the single pole switch) to the common terminal of the 3-way. if you are using a dual 3-way, just leave one of the traveler terminals unused.
In either case, the white (neutral) and ground leads are left connected, just adding a pigtail from the grounds to the new switch.

I was just looking at light switches last night at Home Depot. There's enough options to make your head spin.
Photosensitive light switches are mainly used for outdoor applications, but some look like they should do fine indoors if oriented properly.
