“Amazing, small and effective break beam sensor. It has a great response time and worked fantastic for my coin counter project. Would highly recommend for anyone wanting something like this for a project”
“Working reliably well in the 50cm range and even up to 55cm. When in side-by-side comparison, it even seemed to have more protruded LEDs than the 5mm LEDs sold by PiHut(https://thepihut.com/products/ir-break-beam-sensor-5mm-leds), which might be helping with the longer, more reliable range. With the PiHut product I only got it reliably and repeatedly working in 33cm range. Also slightly thicker wires. I bought 35 pairs to use them as an automatic speedometer in a bird flight tunnel in the field to measure natural flight speed as birds break beams in three different sections consecutively.”
“These work perfectly to trigger an Arduino-controller stepper motor. Added short sections of 8mm tube to help ensure a tighter beam for a more precise activation.”
“Arrived quickly. Good price. Service as always great from pimoroni. I bought them to use in an arduino project. They work really well. I have attached a video the prototype.”
“I bought two pairs. They arrived promptly and worked. The transmitter/receivers were set up about 50mm appart. The power was 5 volts from an Arduino and the output detected by Arduino inputs progammed to have internal pull-up resistors. Everything just worked.”
