This light barrier can be read out with Arduino, Raspberry or similar microcontroller. Widely used for motor speed detection, pulse counting, position limiting, etc.
- Using imported slot type optocoupler sensors
- Slot width 10mm.
- In the output status indicator, the high output light is off and the low output light is on.
- With masking, high level output; without masking, low level output.
- Comparator output, clean signal, good waveform, strong driving power, over 15mA.
- Operating voltage 3.3V-5V
- Output form:Digital switching output (0 and 1)
- With mounting hole, easy to install
- Small circuit board PCB size: 2.3cmx2cm
- Using a high voltage LM393 comparator
Pinout:
- OUT: Signal
- GND: Ground
- VCC: Power supply
Installation instructions:
- The OUT pin is low level when there is no object between the photocell and the red LED is on.
- The OUT pin is high level when there is no object between the photocell and the red LED turns off.
- The OUT port can be connected with MCU directly.
Instructions for using the module
- When there is no mask in the module slot, the receiver tube is on and the module DO outputs a low level, when it is masked, the DO outputs a high level.
- The DO module can be connected to a relay to form a limit switch and other functions, or it can be connected to an active buzzer module to form an alarm.
Scope of delivery:
- 1x 10mm light barrier infrared counter sensor module
Development resources
Example - Use LM393 IR Module as Motor Speed Sensor
