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.

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

It depends on the alignment or position of the hand. Motion sensor might cover a verse area. But precision also is needed. I would go for Ultrasonic sensor though. But it's just based on your used case

Hi! Thank you @Joseph Ogbonna @aymen ammari for your input! I’ve decided to go with your suggestion and choose the HC-SR04 👌🏼
