Obstacle Avoidance Sensor Module
- Stock: 20
- Model: Ir-Sensor-Module
- SKU: PL-727
The sensor module adaptable to ambient light, having a pair of infrared emitting and receiving tubes, transmitting tubes emit infrared certain frequency , when the direction of an obstacle is detected ( reflection surface ) , the infrared reflected is received by the reception tube , after a comparator circuit processing , the green light is on , but the signal output interface output digital signal ( a low-level signal ) , you can adjust the detection distance knob potentiometer , the effective distance range of 2 ~ 8cm, 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 , and black and white line tracking and many other occasions. 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 2~8cm, detection angle 35 Detection distance can be performed by adjusting potentiometer 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 . The minimum detection distance where 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.
