Feature
*This product has a pair of infrared launch and receiving pipes. The transmitting tube emits a certain frequency of infrared rays. When the detection direction encounters obstacles (reflected surfaces), the infrared reflection is returned and received. The indicator light will light up, and at the same time, the signal output interface outputs digital signal (a low level signal), which has strong adaptability to the environmental light.
*You can adjust the potentiometer. The sensor interference is small and easy to install and easy to use. It is widely used and is used in many occasions such as robotics, obstacle avoidance cars, assembly line counts, and black and white line tracking.
*The detection distance can be adjusted by the potentiometer knob, the effective distance range is 2 to 30cm, and the working voltage is 3.3V-5V.
*When the module detects the obstacle signal in front, the green indicator light on the circuit board lights up the level, and the OUT port continues to output low level signals. Adjust the device, clockwise the potentiometer, the detection distance increases; the counterclockwise potentiometer will decrease.
*The sensor actively infrared reflection detection, so the target's reflectance and shape are the key to the detection distance. Among them, the black detection distance is the smallest, the largest in white; the small area of the small area is small and the distance is large.
