Question

What are the reflective and through-beam sensing methods?

Answer



Between similar mediums, ultrasonic waves move straight forward, but when the mediums differ, the waves will either reflect or pass through at the border. What the waves do depends on the type and shape of the medium.

In normal atmosphere, reflection from any object (even human bodies) is well transmitted so detection of that object is easy.
