Oiyagai 5pcs IR Infrared Barrier Module Sensor Obstacle Avoidance for Arduino Intelligent Car Robot

Description: 1.When the module detects an obstacle in front of the signal, the green light on the level of the board, while the OUT port of the output signal continues low level, the module detects the distance 2 ~ 30cm, detection angle 35 °, the distance can be adjusted in the clockwise direction of the adjustment potentiometer to detect the increased distance; Counterclockwise to adjust the potentiometer to reduce the detection distance. 2.The active infrared sensors for detecting the reflected, and hence the shape of the reflectivity of the target detection range is critical. The minimum detection distance which is black, maximum white. 3. The output port of the OUT sensor module can be directly connected to the IO port of the microcontroller, you can directly drive a 5V relay; Connection: VCC-VCC; GND GND-; OUT-IO. 4.Use the LM393 comparator, stable. 5.Can be used for 3 to 5 V DC power supply modules. When the power is turned on, the red power light turns on. 6.With 3mm screw holes, easy and fixed installation. 7.Size of the card: 4.7CM x1.4CM. 8.Each sending module comparing the threshold voltage has been adjusted by the potentiometer is good, not exceptional circumstances, do not arbitrarily adjust the potentiometer. Specification: Hardware: PCB card and electronic component. Operating Voltage: 3.3-5V. Effective Distance: 2-30cm. Detection angle: 35 °. Weight (kg): 0.034. VCC: 3.3V-5V external voltage (can be directly connected to 5v MCU and 3.3v MCU). GND: GND External. OUT: small card digital output interfaces (0 and 1). Package Included: 5 x Infrared Obstruction Avoidance Sensor
