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.
- Flexible operating voltage of 3.3V to 5V
- Digital output (0V or 3.3V)
- Utilize LM393 comparator
- Dimension of 3.2cm * 1.4cm
1x IR Encoder Speed Motion Sensor Module
