Infrared (IR) Obstacle Avoidance Sensor

• When the module detects obstacles in front of the signal, the circuit board green indicator light level, while the OUT port continuous output low-level signals, the module detects a distance of 2 ~ 35cm, detection angle 35 , the detection distance can be potential adjustment with adjustment potentiometer clockwise, the increase in detection distance; counterclockwise adjustment potentiometer, the detection distance decreased.
• the sensor active infrared reflection detection, target reflectivity and shape of the detection distance of the key. The black minimum detection range, white maximum; small area object distance is small, a large area from the large.
• The sensor module output port OUT can be directly connected with the microcontroller IO port can also be driven directly to a 5V relay; Connection: VCC-VCC; GND-GND; OUT-IO
• The comparator using LM393, stable;
• 3-5V DC power supply module can be used. When the power is turned on, the red power LED is lit;
• With the screw holes of 3mm, easy to install;
• Board : 3.1cm x 1.5cm
• Each module in the delivery has threshold comparator voltage adjustable via potentiometer, special circumstances, please do not adjust the potentiometer.

• VCC external 3.3V-5V voltage (can be directly connected with the a 5v microcontroller and 3.3v microcontroller)
• GND external GND
• OUT board digital output interface (0 and 1)

• Supporting DuPont line length about 20CM
