The module features a pair of IR emitter and receiver diodes. The emitter sends out 38kHz infrared light pulses. When the IR light hits an obstacle and reflects back to the receiver, the module outputs LOW (0). When no reflection is detected, it outputs HIGH (1).\u003cbr\u003e\n\u003cbr\u003e\nDetection range of 2-40cm is adjustable via the onboard potentiometer. The 35° effective angle provides wide coverage. 3.3V~5V wide voltage support makes it compatible with Arduino, ESP32, STM32, and other mainstream boards.\u003cbr\u003e\n\u003cbr\u003e\nThe module supports EN enable control. When EN=1, the sensor is disabled; when EN=0, it's active. The default jumper cap connects EN to GND (always on). Remove the jumper to control the sensor via an MCU IO pin.\u003cbr\u003e\n\u003cbr\u003e\nWhether for smart car obstacle avoidance, black\/white line tracking, anti-drop, product counting, conveyor belt cutting, or liquid level detection, the KY-032 delivers reliable obstacle detection.\u003c\/p\u003e\n\n\u003cp class=\"word-break white-space mt-10\" style=\"text-align:left;color:#434649;font-size:20px;font-weight:bold;\"\u003e❓ Why can't my sensor detect black objects or why is the range so short?\u003c\/p\u003e\n\n\u003cp class=\"word-break white-space mt-10\" style=\"text-align:left;color:#434649;font-size:20px;font-weight:normal;\"\u003eIR light reflectivity depends on the object's color.
