They work\nby having an emitter side that sends out a beam of human-invisible IR light,\nthen a receiver across the way which is sensitive to that same light. When\nsomething passes between the two, and its not transparent to IR, then the\n'beam is broken' and the receiver will let you know. Compared to PIR sensors,\nbreakbeams are faster and allow better control of where you want to detect the\nmotion. Compared to Sonar modules, they're less expensive. However, you do\nneed both emitter and receiver on opposite sides of the area you want to\nmonitor. This is the 3mm IR version. It works up to 25cm \/ 10\". You can power\nit from 3.3V or 5V, but 5V will get you better range and is what we suggest.\nThe receiver is open collector transistor output which means that you do need\na pull up resistor if you want to read a digital signal off the signal wire.\nMost microcontrollers have the ability to turn on a built in pull up resistor.\nIf you do not, connect a 10K resistor between the white wire of the receiver\nand the red wire. If you want to control a relay or LED or whatever, it can\nsink up to 100mA to ground\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eSimple way to detect motion\u003c\/li\u003e\n         \u003cli\u003eFaster than PIR sensors and allow better control of where you want to detect the motion\u003c\/li\u003e\n         \u003cli\u003eWorks up to 10 inches\u003c\/li\u003e\n         \u003cli\u003eOpen collector transistor output receiver\u003c\/li\u003e\n  \u003c\/ul\u003e","brand":"Adafruit","offers":[{"title":"Default Title","offer_id":43650280554676,"sku":"B01BU6YBWU","price":98.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0595\/9906\/1172\/files\/B01BU6YBWU.jpg?v=1728889602","url":"https:\/\/auspowers.com\/products\/adafruit-ir-break-beam-sensor-3mm-leds-ada2167","provider":"AusPower Australia","version":"1.0","type":"link"}
