Dear all,
i am a completely beginner about sensor and connecting sensor to a computer. Please don't mind that may be i am asking some stupid questions.
I am doing a project which need sensor to detect whether a person is standing inside a specific area.
If the person is standing inside that area, a device which have pwoer supply will turn on and also a C++/flash program inside a computer will run.
If the person then stand outside the area, we device will turn off and the program inside a computer will stop.
Could anyone tell me that which sensor i should use and how to connect it to the device to control on/off and connect into a computer and let the program to get the variable?
Thanks very much
