INFRARED OBSTACLE AVOIDANCE IR SENSOR MODULE

The sensor module adaptable to ambient light, having a pair of infrared emitting and receiving LEDs, transmitting LED emit infrared certain frequency, when the direction of an obstacle is detected (reflection surface), the infrared reflected is received by the reception LED, After a comparator circuit processing, the obstacle light is on, but the signal output interface output digital signal (a low-level signal), you can adjust the detection distance trim potentiometer, the effective distance range of 2 ~ 20cm, the working voltage of 3.3V- 5V.

Detection range of the sensor can be obtained by adjusting potentiometer, with little interference, easy to assemble, easy to use features, can be widely used in robot obstacle avoidance, avoidance car, line count, black and white line tracking and many other applications.

When the module detects an obstacle in front of the signal, the obstacle indicator lights on the board level, while the OUT port sustained low signal output, the module detects the distance 2 ~ 20cm, detection angle 35 °, the distance can detect potential is adjusted clockwise adjustment potentiometer, detects the distance increases; counterclockwise adjustment potentiometer, reducing detection distance.

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, 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,comparators LM393\LM358, stable, the module can be 3-5V DC power supply.

When the power is turned on, the red power indicator lights, with the screw holes 3mm, easy fixed installation. added extra mosfet on board so you can connect any external load upto 3.5A Pick load and upto 2.5A constant load without external relay module.
