Type : Diy Smart Car Robot Reflective Photoelectric Style : New Smart Electronics Model Number : Obstacle avoidance sensor DIY Supplies : ELECTRICAL Brand Name : Gaqqee Certification : CE Origin : Mainland China Feature 1 : 3 Pin IR Infrared Sensor Module Feature 2 : Obstacle Avoidance Sensor Module Feature 3 : IR Infrared Obstacle Avoidance Sensor Module Feature 4 : For Arduino Smart Car Robot Smart Electronics Diy Smart Car Robot Reflective Photoelectric 3 Pin IR Infrared Obstacle Avoidance Sensor Module For Arduino Instructions for use: 1. When the module detects the obstacle signal in front, the green indicator on the circuit board The indicator light lights up, and the OUT port continues to output low-level signals. The module has a detection distance of 2-30cm and a detection angle of 35. The detection distance can be adjusted by a potentiometer. Adjust the potentiometer clockwise to increase the detection distance; counterclockwise Adjust the potentiometer to reduce the detection distance. 2. The sensor actively detects the infrared reflection, so the reflectivity of the target and Shape is the key to detecting distance. Among them, the black detection range is small, and the white is large; the distance of a small area object is small, and the distance of a large area is large. 3. The output port OUT of the sensor module can be directly connected to the l0 port of the single-chip microcomputer That is, it can also directly drive a 5V relay; connection method: vCC-VCC GND-GND 0UT-10 4. The comparator adopts LM393, which works stably 5. 3-5V DC power supply can be used to supply power to the module. When the power is connected When connected, the red
