{"product_id":"pl4-sen-00241","title":"Infrared Emitters and Detectors","description":"\u003cp\u003eSide-looking Infrared Emitters and IR Detectors. These simple devices operate at 940nm and work well for generic IR systems including remote control and touch-less object sensing. Using a simple ADC on any microcontroller will allow variable readings to be collected from the detector. The emitter is driven up to 50mA with a current limiting resistor as with any LED device. The detect is a NPN transistor that is biased by incoming IR light.\u003c\/p\u003e\n\n\u003cp\u003e**Datasheets:**\u003c\/p\u003e\n\n\u003cp\u003e* [ IR Emitter](http:\/\/www.sparkfun.com\/datasheets\/Components\/LTE-302.pdf) (Yellow dot)\u003cbr\u003e\n* [ IR Detector](http:\/\/www.sparkfun.com\/datasheets\/Components\/LTR-301.pdf) (Red dot)\u003c\/p\u003e\n\n\u003cp\u003e**Applications:**\u003c\/p\u003e\n\n\u003cp\u003e* [ IR Schematic](http:\/\/www.reconnsworld.com\/ir_ultrasonic_basicirdetectemit.html) - Basic object detection schematic\u003cbr\u003e\n* [Robot Room](http:\/\/www.robotroom.com\/Infrared555.html) - Excellent website with lots of goodies\u003c\/p\u003e\n\n \u003cp\u003eSold as a **pair**, with one Emitter and one Detector.\u003c\/p\u003e\n\n\u003cp\u003e**Videos**\u003c\/p\u003e","brand":"PuriLite","offers":[{"title":"Default Title","offer_id":39739982151861,"sku":"PL4-SEN-00241","price":8.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0526\/9553\/1701\/products\/00241-02.jpg?v=1618430325","url":"https:\/\/getcahits.com\/zh\/products\/pl4-sen-00241","provider":"PuriLite","version":"1.0","type":"link"}
