Description
Highlight
  • Sense for object between the IR emitter and IR receiver
  • count the number of obstruction in a given time frame
  • Flexible operating voltage of 3.3V to 5V
  • Digital output (0V or 3.3V)
  • Utilize LM393 comparator

The speed motion sensor utilize a groove IR optocoupler to sense for object between the IR emitter and IR receiver on-board. This methodology allow the module to count the number of obstruction in a given time frame. This characteristic made it very suitable for measuring the speed of rotation.

The digital output is in LOW state when the sensor is not obstructed and the LED will be light up. Digital output will be in HIGH state when the sensor is covered and the LED will be turn off. An on-board potentiometer is available to adjust the sensitivity of the sensor.

Technical details:

  • Operating voltage of 3.3V to 5V
  • Digital output (0V or 3.3V)
  • Utilize LM393 comparator
  • using imported slot type optocoupler sensor
  • The groove width is 10mm.
  • There is an output status indicator, the output high level light is off, and the output low level light is on.
  • there is occlusion, output high level; no occlusion, output low level.
  • the comparator output, the signal is clean, the waveform is good, the driving ability is strong, more than 15mA.
  • Output form: digital switch output (0 and 1)
  • with fixed bolt holes for easy installation
