MODULE IR INFRARED OBSTACLE AVOIDANCE SENSOR

Module IR Infrared Obstacle Sensor Halangan Rintangan



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 .

3 . the output port OUT sensor module can be directly connected to the microcontroller IO port ,



you can directly drive a 5V relay ; Connection : VCC-VCC; GND-GND; OUT-IO

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 ;

7. board size : 3.1CM * 1.5CM

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.



Interface Description (3-wire):

1. VCC: external 3.3V-5V voltage (can be directly connected to 5v MCU and 3.3v MCU)

2. GND: GND External

3. OUT: small board digital output interfaces (0 and 1)



Package Include:

1 x Infrared obstacle avoidance module
