True or False: Proximity sensors can count the number of proximate objects in the air.

• A. True
• B. False
• C. Sometimes
• D. Not at all

Answer: (B)

Proximity sensors are designed to detect whether something is nearby within a fixed range. They typically output a simple signal indicating “object present” or not, or sometimes give a distance to the nearest object. They’re not built to count how many objects are in the air at once. Counting requires resolving and distinguishing multiple targets, which is beyond the standard capability of a single proximity sensor. For counting, you’d use a system like a camera with vision processing or a radar/LiDAR setup, or an array of sensors that can track multiple objects. So the statement is false.
