Avoidance Sensor (x10) Product Manual

Module description

The sensor module is highly adaptable to environmental light. It has a pair of infrared emission and receiving tubes that emit infrared at a certain frequency. When the detection direction encounters obstacles (reflection surface), the infrared reflection is received. After the comparator circuit, the green signal will output a digital signal (a low level signal), which can adjust the detection distance through the potentiometer knob with an effective range of 2 to 30 c m and a working voltage of 3.3V-5V.The detection distance of the sensor can be adjusted by a potentiometer, with small interference, easy assembly and use Convenient and other characteristics, can be widely used in the robot obstacle avoidance, obstacle avoidance, obstacle car, assembly line count and black and white line tracking and many other occasions.

Module parameter description

• When the module detects the front obstacle signal, the green indicator light on the circuit board lights the level, and the OUT port continues to output the low level signal. The module detection distance is 2~30cm, and the detection angle is 35°. The detection distance can be adjusted through the potentiometer, and the detection distance increases; the counterclockwise potentiometer and the detection distance is reduced.
• The sensor has active infrared reflection detection, so the reflectivity and shape of the target are the key to the detection distance.Black has the smallest detection distance and the largest white; small object distance and large distance.
• The sensor module output port OUT can be directly connected to the single-chip IO port, or it can directly drive a 5V relay; the connection mode: VCC-VCC; GND-GND; OUT-IO
• The comparator adopts LM393 for stable operation;
• A 3-5V DC power supply can be used to supply the module.The red power indicator is on when the power is on;
• With 3mm screw hole, easy for fixation and installation;
• Circuit board size: 3.2CM*1.4CM
• Each module has adjusted the threshold comparison voltage through the potentiometer at the shipment. Under nonspecial circumstances, do not adjust the potentiometer at will.
