Each sensor has a separate digital I\/O measurable output . This reflection sensor array is designed to be used as a line sensor, but it may also be used as a proximity or reflection sensor. The module serves as a carrier for eight IR emitter and receiver (photo-transistor) pairs that are uniformly placed at 0.35\" inch intervals.\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-UmUCdo2buoc5UoxtuX7lenSZged\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-EdmDdN0avohij7xg3mflmHnHgfV\"\u003eIt works by detecting infrared light that is emitted, reflected, and detected by the synchronous circuit. The intensity of the light is then utilized to determine if an item exists. It can easily distinguish between black and white lines. In other words, when a phototransistor passes through black and white lines, its different conduction levels might produce different output voltages. The value of all 8 outputs is used to determine the position of the tracking line.\u003c\/div\u003e\n\u003cp class=\"heading-2 ace-line old-record-id-LerCdPc5OoPKwJxA6n0lvXcRgag\"\u003e \u003c\/p\u003e\n\u003ch2 class=\"heading-2 ace-line old-record-id-LerCdPc5OoPKwJxA6n0lvXcRgag\"\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-Nm6WdhRLKoQOdOxlqCmlEwEDgXe\"\u003e\n\u003cstrong\u003eHigh-Density Array:\u003c\/strong\u003e 8 sensors spaced at roughly 9.5mm intervals allow the robot to determine not just if it's on a line, but exactly how far from the center it is.\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-R1Ggdv2VhoOr70x3l2Xlrwj0g4f\"\u003e\n\u003cstrong\u003eDual Output Support:\u003c\/strong\u003e Many variants offer both \u003cstrong\u003eDigital (TTL)\u003c\/strong\u003e outputs for simple logic and \u003cstrong\u003eAnalog\u003c\/strong\u003e outputs for PID control and more nuanced path tracking.\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-YEb8dSqKxod8X8xkocLl7VMRgId\"\u003e\n\u003cstrong\u003eAdjustable Sensitivity:\u003c\/strong\u003e Most boards include a potentiometer or a \"key calibration\" function to adapt to different floor materials and ambient lighting.\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-Ny0sdTSmdo3bmzxxTpLlp2BAg3e\"\u003e\n\u003cstrong\u003eStandard Interface:\u003c\/strong\u003e Designed for easy connection with Arduino, Raspberry Pi, and ESP32 using standard 2.54mm or PH2.0 headers.\u003c\/div\u003e\n\u003cdiv class=\"ace-line ace-line old-record-id-FftndTAOHoRpJAxpHiLloJjtgzf\"\u003e\n\u003cstrong\u003eBuilt-in Indicators:\u003c\/strong\u003e Onboard LEDs provide immediate visual feedback for each channel, making debugging without a serial monitor much easier.\u003c\/div\u003e\n\u003cp class=\"heading-2 ace-line old-record-id-BXIpdQO5kodjLQxRURulWdoqgnf\"\u003e \u003c\/p\u003e\n\u003ch2 class=\"heading-2 ace-line old-record-id-BXIpdQO5kodjLQxRURulWdoqgnf\"\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/h2\u003e\n\u003cul start=\"1\" class=\"list-bullet1\"\u003e\n\u003cli class=\"ace-line ace-line old-record-id-FnnBdDp1foZTrCx5setlJMKqguf\" data-list=\"bullet\"\u003e\n\u003cdiv\u003eInput Voltage: 3.3V-5V\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli class=\"ace-line ace-line old-record-id-KM21deG88oaxnrxFGsvl66MugDc\" data-list=\"bullet\"\u003e\n\u003cdiv\u003eSupply current: 100 mA\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli class=\"ace-line ace-line old-record-id-BK7idNJzWouXTTxYEKKl4WSBgec\" data-list=\"bullet\"\u003e\n\u003cdiv\u003e8- way reflective optical sensors\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli class=\"ace-line ace-line old-record-id-VtS6dGNbtoB6g7xC3OWlHK2tgQg\" data-list=\"bullet\"\u003e\n\u003cdiv\u003eOptimal sensing distance: 0.125\" (3mm)\u003c\/div\u003e\n\u003c\/li\u003e\n\u003cli class=\"ace-line ace-line old-record-id-E7imd2Di6obIMYxBsdylgEc4grh\" data-list=\"bullet\"\u003e\n\u003cdiv\u003eMake the output signal cleaner\u003c\/div\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Elegoo","offers":[{"title":"Default Title","offer_id":44081442062527,"sku":"MLE05383","price":89.0,"currency_code":"PHP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0531\/3419\/6927\/files\/MLE05383.jpg?v=1769132350","url":"https:\/\/makerlab.ph\/products\/elegoo-toolhead-pcb-for-neptune-4-neptune-4-pro","provider":"Makerlab PH","version":"1.0","type":"link"}
