Laser Break Beam Sensor
Laser emitter and receiver pair for break-beam object detection; the receiver outputs a signal change when the beam is interrupted. Self-contained alignment simplifies installation compared to separate laser/sensor setups.
Pinout
- Red wire
5VDC supply lead for the break-beam sensor; Adafruit states to connect 5VDC to the red wire and that 3V will not work.
Type · PowerVoltage · 5VDC - Black wire
Ground lead; Adafruit states to connect Ground to the black wire.
Type · GroundVoltage · 0V - Blue wire
Open-collector style output lead. Adafruit states to use a pull-up on the output pin; when the beam is broken, the blue output wire pulls down to ground, and with the pull-up it reads high when the beam is clear.
