Infrared Sensor ตรวจจับวัตถุ ตั้งระยะได้

1. When the module detects an obstacle in front of the signal , the green indicator light on the board level , while low
-level continuous output signal OUT port , the module detects the distance 2 ~ 30cm, detection angle 35 °, the distance can detect potential is adjusted clockwise adjustment potentiometer to detect the distance increases ; counterclockwise to adjust the potentiometer to reduce the detection distance . 2 .active infrared sensors to detect the reflected , and thus the shape of the reflectivity of the target detection range is critical . The minimum detection distance which black , white maximum ; small objects from a small area , a large area from the Grand . 4 .using the comparator LM393, stable ; 5 .can be used for 3
-5V DC power supply modules . When the power is turned on, the red power indicator light ;
6. with the screw holes of 3mm , easy fixed installation ;
8. each module shipments comparing the threshold voltage has been adjusted by the potentiometer is good , not exceptional circumstances, do not arbitrarily adjust the potentiometer. 5 x Infrared obstacle avoidance module
2.Please allow 0
-1cm error due to manual measurement. pls make sure you do not mind before you bid
