Long Range Beam Break Sensor with Reflector Panel, SparkFun Arduino Pro Mini 328 - 3.3V/8MHz. I had a lot of trouble getting this thing working but two things I learned were that the capacitor near the sensor is a MUST and that light pollution is a bitch. Some other sensors need bursts which I weren't ready to figure out how to code. Let's build back better, together! This detection can be used to operate electronic equipment. The coding could probably be nicer looking and so could the soldering. Unless your sensor is big, it can easily get out of alignment....but not this break beam sensor. This is my code for an Arduino with a break beam sensor to control a LED strip. Actually, after testing my first setup I discovered that the effective range was only around 10m. Basically the same functionality between the two. This coding could most likely be prettier but I copy/pasted/edited from other projects, one using a push button to trigger different things for long/short presses. Keeping the laser aimed at the photo-resistor, flip the switch to arm the device and use a finger to break the laser beam (this sounds more exciting than it is). Related Posts. â¦ Capable of handling long distances. This coding could most likely be prettier but I copy/pasted/edited from other projects, one using a push button to trigger different things for long/short presses. I assume that the Arduino input has a pull-up resistor making it default to high when the beam is blocked. 5.1 Adafruit Accessories IR Break Beam Sensor - 3mm LEDs (1 piece) 5.2 Adafruit IR Break Beam Sensor - 5mm LEDs [ADA2168] 5.3 Dakota Alert BBA-4K-Plus IR Break Beam Solar Powered Motion Sensor â¦ A cheap beam break sensor utilising a reflector panel instead of a transmitter / receiver setup.
