Infrared IR Optical Counter Tachometer RPM Speed Measuring Sensor Optocoupler Module

Infrared IR Optical Counter Tachometer RPM Speed Measuring Sensor Optocoupler Module for Arduino

Features:

• Operating Voltage: 3.3V to 5VDC
• Slot Width: 5mm
• Output Signal: Analog and Digital output

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.

Specifications:
