1. The output terminal can be directly connected to the port of a singlechip microcomputer or directly control a 5V booster. Connection method: GND to GND. 2. With a sensitivity adjustment knob, the detection distance can be adjusted according to actual environmental requirements to adapt to different application scenarios. 3. The comparator uses LM393, which operates stably. It can be powered by a 35V power supply. When powered on, 4. When detecting front obstacle signals, the green indicator on the PCB lights up, and the OUT port continuously outputs a signal. The module's detection range is 230 cm, with a detection angle of 35°. The detection distance can be adjusted via the potentiometer: turning it clockwise increases the detection distance, while turning it counterclockwise decreases the detection distance. Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures. Please allow slight dimension difference due to different manual measurement.
