{"title":"4 Channels IR Reflective Sensor","handle":"4-channels-ir-reflective-sensor","url":"/products/4-channels-ir-reflective-sensor","description":"This Elecrow 4-channel IR reflective sensor module combines four infrared emitter/receiver pairs with a mainboard that processes all signals. When an object enters the detection range, the corresponding channel outputs a low (TTL 0) signal and its indicator LED lights up. Each channel has an onboard potentiometer for adjustable detection range from 1mm to 60cm.\n\nThe module runs on 3.3V to 5.5V, making it compatible with both 3.3V and 5V microcontrollers. It is well-suited for robotics applications such as line following, edge detection, and obstacle avoidance.\n\nKey Features\n\n\n4 Independent IR Channels – Each channel has its own IR emitter, receiver, indicator LED, and sensitivity potentiometer\n\nAdjustable Detection Range – 1mm to 60cm, tuneable via onboard potentiometers\n\nTTL Digital Output – Low (0) when object detected, high (1) when clear\n\nWide Voltage Range – 3.3V to 5.5V supply\n\nLED Indicators – Visual feedback for each channel's detection status\n\n\nSpecifications\n\n\nSupply Voltage – 3.3V to 5.5V\n\nSupply Current – >1A recommended\n\nDetection Range – 1mm to 60cm (adjustable)\n\nOutput – TTL digital (active low)\n\nChannels – 4\n\n\nIdeal For\n\nLine-following robots\nEdge detection\nObstacle avoidance\nOmni-directional object sensing\n\n\nPackage Contents\n\n1× 4-Channel IR Reflective Sensor Module\n","vendor":"Elecrow","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3568,"title":"Default Title","sku":"EC-SPS40201S","price":10.98,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":105,"option1":"Default Title"}]}
