- Infrared (IR) break-beam sensors are a simple way to detect motion. They work by having an emitter side that sends out a beam of human-invisible IR light, then a receiver across the way which is sensitive to that same light. When something passes between the two, and its not transparent to IR, then the 'beam is broken' and the receiver will let you know.

- The seco-larm ir break beam sensor is ideal for the front porch and it is easy to wire. Make sure this fits by entering your model number. Moreover, the sensor makes for easy setup and it is easy to mount. Most importantly, the seco-larm irbreak beam sensor has a built-in led indicator, is very helpful and it is secure.
IR BEAM Camera Triggering - High Speed Photography
- https://www.woodselec.com/IRbeam.htm
- Its easy really. All you have to do is place the IR beam in front of your subject. The IR beam is used as an invisible trip wire. Anything that enters the beam is photographed regardless of speed or size. Why use IR Beam triggerring? It's Fast. It's Accurate. (The edge of the beam is the triggering point.)

- An Active Infrared (IR) DSLR Camera Trap uses industry-standard Active IR sensors to detect when an object breaks the beam and sends a signal to a DSLR camera to release the trigger. An Active IR sensor is what is commonly used in home security motion detectors or factory automation systems. Instead of tripping an alarm or a counter, we are going to use the IR …
Detecting an IR Beam Break with the Arduino IR Library
- https://www.righto.com/2010/03/detecting-ir-beam-break-with-arduino-ir.html
- The IR LED is connected to pin 3 through a 100 ohm resistor, the detector is connected to pin 2, and a status LED is connected to pin 13 (if your Arduino board doesn't have it already.) To create the modulated output, simply call irsend.enableIROut (38); to set the PWM to 38kHz, and then irsend.mark (0) to send a mark (i.e. turn the output on).
Laser break, infrared break and passive infrared (PIR
- https://www.versatrigger.co.uk/laserinfraredpir.html
- Infrared break This is another method of "beam break", it uses active infrared (940nm) and again has a receiver and a transmitter. The advantage of this system is that it is invisible to the naked eye and so should not appear in the image (unless they have been specifically modified, all cameras have an infrared filter in front of the sensor element).

- 4 x 100n Ceramic Cap. The prototype circuit board. The mounting arms for the laser and photodiode were made from 25mm perspex tube and a led holder was made from 10mm black derlin with a 2mm hole for the laser beam to enter and a 5mm hole for the photodiode to sit in. This shields the photodiode from external light from the sides.
