Light Sensing Start to a Wireless Camera?
Can I just wire the photocell into the wiring of the battery:
---- 9 volt ---> photocell ----> camera
Or will I "have to" make a circuit on a breadboard or something to control this?
I'm looking for simple and fast on this so if a circuit needs to be made please provide a link or clue as to a schematic I can use or reference.
That photocell can handle 150V max and in the description says "These little sensors make great ambient light triggers (when light in the room turns on, do something)."
Thanks
You can leave an optional "tip" with Mahalo's virtual currency, Mahalo Dollars. If you are asking a difficult question that might require some research, or if you'd like a wide variety of feedback, a higher tip often leads to more answers to your question.

9V - -------------------------------------
... this was when the light is off the photocell is at 10K or so and the electricity will travel down the 4K resistor back into the battery and experience no drainage. Then when the light is on the photocell will drop to 1K resistance and the electrons will take that path across the photocell to the camera.
Will that work and is my logic and understanding on this correct?
Thanks

And all I typed in was "light activated circuit schematic".
