IR Infrared Obstacle Avoidance Sensor Module

Description:

• 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 degree, 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 .
• 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 .
• 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
• Using the comparator LM393, stable
• When the power is turned on, the light is red.
• Widely used in robot obstacle avoidance, obstacle avoidance car, line count and black and white line tracking and so on.
• With the screw holes of 3mm , easy fixed installation.
• Notice:each module shipments comparing the threshold voltage has been adjusted by the potentiometer is good , not exceptional circumstances, do not arbitrarily adjust the potentiometer
