Frequently Asked Questions

Q: What is the Infrared Obstacle Avoidance Sensor Module used for in Arduino projects?

A: This infrared obstacle avoidance sensor module is used to detect objects or surfaces within its adjustable sensing range and send a signal to a connected microcontroller (such as an Arduino). It is commonly used in smart car obstacle avoidance, autonomous robot navigation, and proximity detection systems in DIY electronics projects.

Q: How do I connect the infrared sensor module to an Arduino board?

A: The module uses a simple 3-pin interface — VCC (power), GND (ground), and OUT (digital signal output). Connect VCC to your Arduino's 5V pin, GND to a ground pin, and OUT to any digital input pin on your Arduino. Once connected, you can read the signal output in your sketch to trigger actions when an obstacle is detected.

Q: Can I adjust the obstacle detection distance on this sensor module?

A: Yes! The module features an onboard potentiometer that allows you to fine-tune the infrared detection distance. By turning the potentiometer, you can set the sensor's sensitivity and effective range to match the specific needs of your smart car, robot, or other automation project.

Q: How many sensor modules come in each order?

A: You can choose from three quantity options at checkout: 1 pc, 5 pcs, or 10 pcs. Multipacks are ideal for larger robotics builds or STEM classroom kits where multiple detection points are needed.

Q: Is this module compatible with platforms other than Arduino?

A: Yes. While it is optimized for Arduino, the 3-pin digital output interface makes it compatible with most microcontrollers that support 5V digital I/O, including Raspberry Pi (with a logic level converter), ESP8266, ESP32, and other common development boards.
