{"product_id":"ir-break-beam-sensor-5mm-leds","title":"IR Break Beam Sensor - 5mm LEDs","description":"\u003cp\u003eThis is a 5mm Infrared break-beam sensor. 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 3mm 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 40-50cm 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 yellow and red wires on the receiver. You can try lower resistor values if you need to (if you can't achieve the required distance) but ensure no more than 3.3V is sent to your GPIO pin via the signal line.\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: ~50cm\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: 250mm\u003c\/li\u003e\n\u003cli\u003eWeight (each): ~3g\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e","brand":"The Pi Hut","offers":[{"title":"Default Title","offer_id":43493223137357,"sku":"nkt1787257412210","price":3.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0644\/1182\/8301\/files\/ir-break-beam-sensor---5mm-leds_1.jpg?v=1787257416","url":"https:\/\/www.grandorchard.shop\/products\/ir-break-beam-sensor-5mm-leds","provider":"My Store","version":"1.0","type":"link"}
