ACEIRMC 10pcs IR Infrared Obstacle Avoidance Sensor for Arduino Smart Car Robot IR Transmitting and Receiving Tube Photoelectric Switch
Brand: ACEIRMC
Feature:

1, When the module detects an obstacle in front of the signal, the green indicator lights on the board level, while the OUT port sustained low signal output, the module detects the distance 2 ~ 30cm,

detection angle 35 °, the distance can detect potential is adjusted clockwise adjustment potentiometer, detects the distance increases; counterclockwise adjustment potentiometer, reducing detection distance.

2, The sensor active infrared reflection detection, target reflectivity and therefore the shape is critical detection distance.

Where the minimum detection distance black, white, maximum; small objects away from a small area, a large area from the Grand.

3, the sensor module output port OUT port can be directly connected to the microcontroller IO can also be directly drive a 5V relay; Connection: VCC-VCC; GND-GND; OUT-IO

4, comparators LM393, stable;

5, the module can be 3-5V DC power supply. When the power is turned on, the red power indicator lights;

6, with the screw holes 3mm, easy fixed installation;

7, board size: 3.2CM * 1.4CM

8, each module has been shipped threshold comparator voltage adjusted by potentiometer good, non-special case, do not adjustable potentiometer.

PIN Description:

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

2 GND GND External

3 OUT small board digital output interface (0 and 1)

Package Includes：

10 * IR Infrared Obstacle Avoidance Sensor Module
The output port OUT sensor module can be directly connected to the microcontroller IO port, you can directly drive a 5V relay.
It has a pair of infrared transmitting and receiving tube, tube infrared emit a certain frequency, when detecting direction meet with obstacles (reflecting surface), reflected infrared receiving tube, after the comparator circuit processing, green indicator will light up, at the same time signal output interface to output digital signal (a low level signal).
Can be used for 3-5V DC power supply modules. It has red power indicator.
the Sensor module detects the distance 2 ~ 30cm, detection angle 35 °, the distance can detect potential is adjusted
IR Infrared Obstacle Avoidance Sensor Module can be widely used in robot obstacle avoidance, obstacle avoidance car, line count, and black and white line tracking and so on.
