    Hi

    I want to turn on and turn off my LED table study lamp by moving my hand over a sensor. Hand over tuns on and hand over again to turn off. Do I need a infrared sensor and a flip flap?

    What do you suggest? A simple one and as small as possible!!

    I am really sorry i missed your comment.
    I dont have experince with IR sensor and Flip Flop circuit to be able to advise you on it.
    Easiest thing that i can suggest would be to use an Ultrasonic sensor to detect if you hand is there or not and it works in the dark.
