Re: Object detection / surface scanning

soo... apparently the ir receivers i could find only have 45° angle of detection and i had really hoped to find some addressable ir - rb strip all in one but off course thats not a thing. so i could wire up the leds individually i need be but the angle on the receiver means not only do i have to wir...

Re: Object detection / surface scanning

How about ultrasonic or IR reflective distance sensors at either end of the shelf? You'd probably only be able to predict where a maximum of two objects were on the shelf but it might serve your purpose. Another suggestion would be a film similar to that used on touch screens. An even lower tech wa...
