It is equipped with a pair of infrared transmitting and receiving tubes. The transmitting tube emits infrared rays at a specific frequency. When encountering an obstacle (reflective surface) in the detection direction, the infrared rays are reflected back and received by the receiving tube. After processing by the comparator circuit, the green indicator light will turn on, and the signal output interface will output a digital signal (a low-level signal). The detection distance can be adjusted via the potentiometer knob, with an effective range of 2–30 cm, and the operating voltage is 3.3V–5V. The sensor’s detection distance is adjustable via the potentiometer, and it offers the advantages of low interference, easy assembly, and convenient use. It can be widely applied in numerous scenarios such as robot obstacle avoidance, obstacle-avoiding smart cars, assembly line counting, and black\/white line tracking.\u003c\/div\u003e\u003cdiv style='font-family:ui-sans-serif, system-ui, sans-serif, \"Apple Color Emoji\", \"Segoe UI Emoji\", \"Segoe UI Symbol\", \"Noto Color Emoji\";font-size:16px;font-weight:400;line-height:24px;text-align:start;white-space:normal;color:rgb(0, 0, 0);background-color:rgba(0, 0, 0, 0);margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;padding:0px;padding-bottom:0px;padding-top:0px;padding-left:0px;padding-right:0px;display:block' align=\"start\"\u003e\u003c\/div\u003e\u003ch2 style='font-family:ui-sans-serif, system-ui, sans-serif, \"Apple Color Emoji\", \"Segoe UI Emoji\", \"Segoe UI Symbol\", \"Noto Color Emoji\";font-size:16px;font-weight:400;line-height:24px;text-align:start;white-space:normal;color:rgb(0, 0, 0);background-color:rgba(0, 0, 0, 0);margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;padding:0px;padding-bottom:0px;padding-top:0px;padding-left:0px;padding-right:0px;display:block' align=\"start\"\u003eModule Parameters\u003c\/h2\u003e\u003cdiv style='font-family:ui-sans-serif, system-ui, sans-serif, \"Apple Color Emoji\", \"Segoe UI Emoji\", \"Segoe UI Symbol\", \"Noto Color Emoji\";font-size:16px;font-weight:400;line-height:24px;text-align:start;white-space:normal;color:rgb(0, 0, 0);background-color:rgba(0, 0, 0, 0);margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;padding:0px;padding-bottom:0px;padding-top:0px;padding-left:0px;padding-right:0px;display:block' align=\"start\"\u003e\u003c\/div\u003e\u003col style='font-family:ui-sans-serif, system-ui, sans-serif, \"Apple Color Emoji\", \"Segoe UI Emoji\", \"Segoe UI Symbol\", \"Noto Color Emoji\";font-size:16px;font-weight:400;line-height:24px;text-align:start;white-space:normal;color:rgb(0, 0, 0);background-color:rgba(0, 0, 0, 0);margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;padding:0px;padding-bottom:0px;padding-top:0px;padding-left:0px;padding-right:0px;display:block' align=\"start\"\u003e\n\u003cli style='font-family:ui-sans-serif, system-ui, sans-serif, \"Apple Color Emoji\", \"Segoe UI Emoji\", \"Segoe UI Symbol\", \"Noto Color Emoji\";font-size:16px;font-weight:400;line-height:24px;text-align:start;white-space:normal;color:rgb(0, 0, 0);background-color:rgba(0, 0, 0, 0);margin:0px;margin-bottom:0px;margin-top:0px;margin-left:0px;margin-right:0px;padding:0px;padding-bottom:0px;padding-top:0px;padding-left:0px;padding-right:0px;display:list-item' align=\"start\"\u003e\u003cp\u003eWhen the module detects a signal from a forward obstacle, the green indicator light on the circuit board will illuminate, and the OUT port will continuously output a low-level signal.
