These sensors are great for projects which need a simple and reliable way to detect motion or someone\/something passing through an area. We also sell a 5mm version.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\u003cstrong\u003eThe pack includes both parts to create a single 'beam'\u003c\/strong\u003e with a sensor each side (you don't need to buy two of these to create a break-beam)\u003c\/em\u003e\u003c\/p\u003e\n\u003cp\u003eThe sensors work as an emitter-receiver setup - the emitter sends IR light out which is detected by the receiver. When something\/someone passes in front of the IR light (breaking the beam), the receiver detects the change and can be used as a trigger for your project.\u003c\/p\u003e\n\u003cp\u003eThe emitter and receiver can be around 20-25cm apart - anything further and results can be unreliable.\u003c\/p\u003e\n\u003cp\u003eIt's best to power these at 5V to get the best performance and range, however 3.3V works as well. Trial and error testing suggested!\u003c\/p\u003e\n\u003cp\u003eTo read a digital signal from the receiver, use a pull-up resistor (10k suggested) between the white and red wires on the receiver. \u003cspan data-mce-fragment=\"1\"\u003eYou can try lower resistor values if you need to (if you can't achieve \u003c\/span\u003e\u003cspan data-mce-fragment=\"1\"\u003ethe required distance) but ensure no more than 3.3V is sent to your GPIO pin via the signal line.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\n\u003cdiv id=\"technical-details\" class=\"panel-collapse collapse in-md in-lg\"\u003e\n\u003cul\u003e\n\u003cli\u003eVoltage: 5V (3.3V also works)\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eEmitter Current Draw: 10mA @ 3.3V, 20mA @ 5V\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eOutput Current Capability of receiver: 100mA sink\u003c\/span\u003e\u003c\/li\u003e\n\u003cli\u003eDistance: ~25cm\u003c\/li\u003e\n\u003cli\u003eResponse: \u0026lt;2 ms\u003c\/li\u003e\n\u003cli\u003eAngle: 10°\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eDimensions: 20mm x 10mm x 8mm\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003eCable: 234mm\u003c\/li\u003e\n\u003cli\u003eWeight (each): ~3g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul id=\"product-files\"\u003e\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"The Pi Hut","offers":[{"title":"Default Title","offer_id":43493223071821,"sku":"jjs1787257411210","price":1.85,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/1182\/8301\/files\/ir-break-beam-sensor---3mm-leds_1.jpg?v=1787257415","url":"https:\/\/www.grandorchard.shop\/products\/ir-break-beam-sensor-3mm-leds","provider":"My Store","version":"1.0","type":"link"}
