Working Principle
Infrared beam sensors operate by emitting, propagating, and
receiving infrared radiation to detect objects. Here's a detailed
breakdown of their functionality:
Infrared Emission:
An infrared emitter generates a focused beam of infrared light.
Beam Propagation:
The emitted beam travels through a predetermined path, creating an
invisible detection line.
Target Interaction:
When an object crosses this path, it interacts with the beam
through reflection, absorption, or scattering of the infrared
light.
Reflection or Scattering:
The infrared receiver within the sensor captures the reflected or
scattered light from the object.
Signal Processing:
The sensor processes the received signal, analyzing parameters such
as signal strength and frequency to determine the presence,
distance, or other relevant characteristics of the object.
Output Results:
The analyzed data is converted into electrical or digital signals,
which can then trigger specific actions, alarms, or data logging.
