Infrared IR Optical Counter Tachometer RPM Speed Measuring Sensor Optocoupler Module

Infrared IR Optical Counter Tachometer RPM Speed Measuring Sensor Optocoupler Module for Arduino
The Encoder speed sensor, composed of an IR LED and an IR Photodiode, functions as a Photo-Coupler or Opto-Coupler. It detects objects using infrared radiation and consists of LEDs for power and digital output indication. The digital output signal becomes HIGH when an object obstructs the sensor gap and LOW when there’s no obstruction.
 

Features:

Operating Voltage: 3.3V to 5VDC: The sensor operates within a voltage range of 3.3V to 5VDC, making it compatible with various microcontroller platforms.
Slot Width: 5mm: The width of the sensing slot is 5mm, providing adequate space for detecting objects passing through the sensor.
Output Signal: Analog and Digital output: The sensor provides both analog and digital output signals, offering flexibility in interfacing with different types of microcontrollers or processing units.
