10 Pieces Infrared Obstacle Avoidance Sensor Module for Smart Car Robot and Arduino, 3 Wires, Reflective

Features:

1. When the module detects an obstacle in front of the signal, the green LED on the board illuminates, while the OUT port maintains a low signal output. The module detects objects at a distance of 2-30cm.

The detection angle is 35°. The detection distance is adjusted clockwise using the potentiometer to increase the detection distance; counterclockwise using the potentiometer to decrease the detection distance.

2. The sensor uses active infrared reflection detection. The target's reflectivity, and therefore its shape, determines the critical detection distance.

The minimum detection distance is indicated by black, white, and maximum; small objects are detected in a small area, large objects in a large area.

3. The sensor module's output port can be directly connected to a microcontroller's I/O and can also directly drive a 5V relay. Connection: VCC-VCC;

GND-GND; OUT-IO

4, LM393 comparators, stable;

5, the module can be powered by a 3-5V DC supply. When the power is on, the red power indicator light illuminates;

6. With 3mm screw holes, easy fixed installation;

7. Board size: 3.2 CM * 1.4 CM

8. Each module is shipped with the threshold comparator voltage adjusted by a potentiometer. In some cases, there is no adjustable potentiometer.
