the reflected infrared light of a target object, and outputs detection status via both analog and digital signals. Its unique design incorporates an onboard adjustable potentiometer for tuning the sensitivity of the digital output, allowing users to adjust the sensor's parameters as needed for increased flexibility and precision. This product is suitable for applications such as object detection, line tracking, distance measurement, and automation systems.\u003c\/p\u003e\n\u003cdiv style=\"\n  background: #f3f8ff;\n  border: 1px solid #cfe1ff;\n  border-left: 4px solid #1f6fe5;\n  border-radius: 8px;\n  padding: 14px 16px;\n  margin: 24px 0;\n\"\u003e\n  \u003cstrong style=\"\n    display: block;\n    color: #0d47a1;\n    font-size: 15px;\n    margin-bottom: 6px;\n  \"\u003e\n    Note\n  \u003c\/strong\u003e\n\n  \u003cspan style=\"\n    color: #2c2c2c;\n    font-size: 14.5px;\n    line-height: 1.6;\n  \"\u003e\n    The rear potentiometer adjusts detection distance (sensitivity). It is pre-set at the factory to a comparator threshold voltage of 1.65V. Do not adjust the potentiometer unless necessary. Valid voltage range: 0.3V ≥ 1.65V ≤ 2.15V. Beyond this range — when \u0026gt; 2.15V, the red LED will stay on; when \u0026lt; 0.3V, the red LED will stay off, causing detection failure. (The potentiometer voltage can be measured at the comparator LM393 inverting terminal according to the schematic.)\n  \u003c\/span\u003e\n\u003c\/div\u003e\n\u003ch2 data-id=\"Features\"
