IR Infrared Obstacle Avoidance Sensor Module, 20Pcs IR Infrared Sensor 3-Wire Infrared Proximity Sensors Reflective Photoelectric Sensor Modules IR Tracking Sensor for Arduino Smart Car Robot

Highlights

• 【Material】20 infrared sensor modules are made of high-quality electronic accessories, with nickel-plated surface, which has superior oxidation resistance, conductivity and durability; the detection range of the sensor adopts LM393 chip, which can be
• 【Easy to Use】the OUT output port of the IR proximity sensor can be directly connected to the I/O port of the microcontroller, or can directly drive a 5V relay; connection method: VCC-VCC; GND-GND; OUT-IO; 3 to 5V DC can be used Power supply; with 3mm
• 【Adjustable Distance】When the signal module detects the signal of the obstacle ahead, the green indicator light on the circuit board is on, and the OUT port continues to output a low-level signal
• The detection distance can be adjusted with the potentiometer, clockwise to increase the detection distance, reverse The counterclockwise direction reduces the detection distance.
• 【Widely Used】The detection distance of obstacle avoidance sensor can be adjusted by the potentiometer. It has the characteristics of small interference, easy assembly, and convenient use.
• IR sensor module can be widely used in many occasions such as robot obstacle avoidance, obstacle avoidance car, assembly line counting, and black and white line tracking.
• 【Note】The Infrared obstacle avoidance module actively detects infrared reflections, so target reflectivity and shape are key to detection range. The black detection range is the smallest, and the white is the largest; the distance between small-area
