Adafruit IR Beam Sensors With Premium Cable Ends, 3mm LEDs, 2167
The description of this item has been automatically translated. If you have any questions, please feel free to contact us.
Product overview IR break beam sensor (3 mm) for motion detection with light barrier. An infrared transmitter and a matching receiver detect when the beam is interrupted, e.g. B. by an object or a person.
Characteristics- Faster and more targeted motion detection than PIR sensors
- More cost-effective than ultrasonic modules
- Range up to approx. 25cm (10")
- Operates on 3.3V or 5V (5V recommended for maximum range)
- Output of the receiver as an open collector transistor (requires pull-up resistor)
- Suitable for direct control of relays, LEDs etc. (up to 100 mA to GND)
- Cabling with high-quality wire ends, easy to cut if necessary
Instructions for use- For digital output, either enable internal pull-up of the microcontroller or use external 10 kΩ resistor between signal (white) and VCC (red).
- The transmitter and receiver must be opposite each other to cover the monitored area.
Variants- This version: 3mm IR break beam sensor
- Alternative: 5 mm version with slightly longer reach
