1 if the module detects obstacles ahead signal , the Green led is lit on the Board level OUT port at low level output signal ,the module detects the distance 2~30cm , detection angle of 35 , the detection range can be adjusted by potentiometerclockwise adjustment potentiometer , detection range increases counterclockwise adjustment potentiometer , detectionrange reduction .
2 , active infrared reflection sensor detection , so the reflectivity and shape is the key to detecting distance . Blackdetection range minimum , white the largest small objects from small and large distances .
Output OUT 3 , the sensor module can be directly connected to the monolithic integrated circuit IO mouth , or you candirectly drive a 5V relay ; connections : VCC-V CC; GND-GND;OUT-IO
4 , comparator LM393 , stable ;
5 , 3-5V DC power supply to power the modules can be used . When the power is switched on , the red power led is lit ;
6 , 3mm the screw holes for easy fixing , installing ;
7 , Board size : 3.2CM*1.4CM
8 , each module is shipped already compare the threshold voltage by adjusting the potentiometer , an exceptionalsituation , do not arbitrarily adjust potentiometer ...
