A motion sensor or an ultrasonic sensor to correctly detect a hand at about 1.3 meters?

Hello everyone
I would like to know what would be better to correctly detect a hand at about 1.3 meters? A motion sensor or an ultrasonic sensor?🧐 I have the HC-SR04 and the HC-SR501. It's for my laser harp.

Best regards.
Solution
I think HC-SR04 is the best Solution cuz its working rang is ip to 3m so it will work fine
