Cogfs 10 Pcs Smart car barrier avoiding sensor module optoelectronic reflection sensor

Feature *This product has a pair of infrared launch and receiving pipes. The transmitting tube emits a certain frequency of infrared rays. When the detection direction encounters obstacles (reflected surfaces) the infrared reflection is returned and received. The indicator light will light up and at the same time the signal output interface outputs digital signal (a low level signal) which has strong adaptability to the environmental light. *You can adjust the potentiometer. The sensor interference is small and easy to install and easy to use. It is widely used and is used in many occasions such as robotics obstacle avoidance cars assembly line counts and black and white line tracking. *The detection distance can be adjusted by the potentiometer knob the effective distance range is 2 to 30cm and the working voltage is 3.3V-5V. *When the module detects the obstacle signal in front the green indicator light on the circuit board lights up the level and the OUT port continues to output low level signals. Adjust the device clockwise the potentiometer the detection distance increases; the counterclockwise potentiometer will decrease. *The sensor actively infrared reflection detection so the target s reflectance and shape are the key to the detection distance. Among them the black detection distance is the smallest the largest in white; the small area of the small area is small and the distance is large. Specification Connection: The output port out of the sensor module can be connected directly with the single -chip IO port or it can directly drive a 5V relay directly Connection: VCC-VCC; GND-GND; OUT-IO Comparison: LM393 stable work; Power: 3-5V DC power can be used to power the module. When the power supply is turned on the red power indicator lights lit Installation: It has a screw hole of 3mm which is convenient for fixing and installation Circuit board size: 3.2cm*1.4cm Quantity: 10PCS Note: Each module has adjusted the threshold comparison voltage through the potentiometer at the delivery. It is not special case. Do not adjust the potentiometer at will.
