I want such a setup that when i touch the sensor, a circuit (including batteries) kept at a distance of less than 6 m gets complete and the bulb lights up and when i leave the finger from sensor the circuit breakes and the bulb stops glowing. i.e. the switch of the circuit in in the control of my hand.The sensor should be as small as possible.
I wanted to ask which sensor should i buy and how much it would cost and how can i prepare such a setup.(the sensor should be as cheap as possible)
