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.
