HALJIA IR Infrared Obstacle Avoidance Sensor Module Reflective photoelectric for RC Smart Car Robot

• 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).
• The detection distance can be adjusted with the potentiometer knob, the potentiometer is adjusted clockwise, the sensing distance is increased, and the potentiometer is adjusted counterclockwise to decrease the sensing distance. Detection distance 2 ~ 30cm, detection angle 35 °.
• The output output OUT of the sensor module can be connected directly to the MCU-IO port or directly control a 5 V relay, connection mode: VCC-VCC, GND-GND, OUT-IO.
• The module can be operated with a 3-5 V DC power supply. When the unit is turned on, the red power indicator lights up.
• With the comparator LM393, stable operation. This IR Infrared Obstacle Avoidance Sensor Module can be widely used in many obstacles such as robotic obstacle avoidance, obstacle avoidance trolley, piping counter and black and white line tracking.

Features: 1. When the module detects an obstacle in front of the signal , the green indicator light on the board level , while low-level continuous output signal OUT port , the module detects the distance 2 ~ 30cm, detection angle 35 °, the distance can detect potential is adjusted clockwise adjustment potentiometer to detect the distance increases ; counterclockwise to adjust the potentiometer to reduce the detection distance. 2 . Active infrared sensors to detect the reflected , and thus the shape of the reflectivity of the target detection range is critical. The minimum detection distance which black , white maximum ; small objects from a small area , a large area from the Grand. 3 . The output port OUT sensor module can be directly connected to the microcontroller IO port , you can directly drive a 5V relay ; Connection : VCC-VCC; GND-GND; OUT-IO. 4 . Using the comparator LM393, stable . 5 . Can be used for 3-5V DC power supply modules. When the power is turned on, the red power. 6. With the screw holes of 3mm, easy fixed installation. 7. Board size : 3.2 cm x 1.4 cm. 8. Each module shipments comparing the threshold voltage has been adjusted by the potentiometer is good , not exceptional circumstances, do not arbitrarily adjust the potentiometer. Interface Description (3-wire) : 1. VCC: external 3.3V-5V voltage (can be directly connected to 5v MCU and 3.3v MCU) 2. GND: GND External 3. OUT: small board digital output interfaces (0 and 1) Package Inculded: 1 x Infrared obstacle avoidance module
