Description

The Infrared Counting Sensor Module is used to count or detect objects that move through the U-shaped detector uprights.

PACKAGE INCLUDES:
  • Infrared Counting Sensor Module
KEY FEATURES OF INFRARED COUNTING SENSOR MODULE  MODULE:
  • IR transmitter/receiver pair
  • LM393 comparator circuit for clean detection
  • LED indicator of detection
  • 3.3 and 5V compatible

The module has an IR transmitter and receiver pair that face each other across a U-shaped housing.  An object moving through these uprights breaks the IR beam.

These modules are typically used to count something as it passes through the uprights.  This could be cogs on a wheel if it is counting revolutions or RPM, or something like pellets dropping through a chute if it is part of a feeder for a pellet stove or rabbit.  Another use is as an optical limit switch or to detect when something is open or closed if it causes an object to move in or out of the beam.

The sensor output is normally LOW and the red LED on the module will be normally lit.  If the IR beam between the uprights is broken, the output goes HIGH and the LED goes off.

Module Connections

The module has a 3 pin header for making connections.

1 x 3 Header 

  • GND – Ground
  • OUT – Output, normally LOW.  Goes HIGH when IR beam is broken
  • VCC – 3.3 – 5V

The module has two holes for mounting.

OUR EVALUATION RESULTS:

While this module is similar in functionality to the less expensive Light Block Sensor Module, the Infrared Counting Sensor Module has much higher and wider detector uprights and a LM393 comparator circuit that make it more robust and flexible in applications it can be used in.
