- Infrared Avoidance Sensor-Potentiometer Adjustment -- The detection range of the sensor can be adjusted with potentiometer, little interference, easy assembly and use.
- Infrared Reflection Sensor-Application Field -- Can be widely used for robot obstacle avoidance, obstacle avoidance car, assembly line, black and white line tracking and many other occasions.
- Infrared Sensor IR-Indicator Light -- When module detects obstacles ahead, the green indicator light on the circuit board is on and at the same time the OUT port outputs low level ; detection distance can be adjusted with potentiometer, clockwise to increase detection distance.
- Infrared Obstacle Avoidance-Detection Range -- Active infrared reflection detecting sensor, so the target reflectivity and shape is the key of the detection range.Black color has the minimum detection range, white has the maximum; small objects have short detection range, large objects have long dete.
- Sensor Module Smart-Module Output -- Sensor module output port OUT can be directly connected to micro-controller IO port, also can drive a 5V relay directly.

The sensor module is adaptable to ambient light. It has a pair of infrared transmitting and receiving tube. Transmitting tube sends out a certain frequency IR which will be reflected when detecting obstacles (reflecting surface) and received by receiving tube. After processing with comparator circuit, green light is on and output interface outputs digital (a low voltage level ). Detection distance can be adjusted with the potentiometer, effective distance range 2~60cm, working voltage 3.3V to 5V.
Features:
Sensor module output port OUT can be directly connected to micro-controller IO port, also can drive a 5V relay directly.
Comparator uses the LM393 chips, stable performance.
Can use 3 to 5V DC power supply.When power on, the red power indicator light is on.
Designed with 3mm screw holes for convenient fixation and easy installation;
Each module has already adjusted threshold compare voltage with potentiometer well, so please do not arbitrarily adjust potentiometer.
Specifications:
Working Voltage: 3.3~5V
Detecting Range: 2~30cm
Detection Angle: 35°
Wiring: VCC-VCC; GND-GND; OUT-IO
Size: 4*1.5cm/1.5*0.6in
