Frequently Asked Questions

Q: What voltage does the IR infrared obstacle avoidance sensor module require?

A: This sensor module operates on a supply voltage of 3.3V to 5V DC, making it compatible with a wide range of microcontrollers including Arduino (5V) and Raspberry Pi (3.3V) platforms.

Q: How does the reflective photoelectric obstacle avoidance sensor work?

A: The module uses a paired IR emitter and photoelectric receiver. The IR emitter transmits infrared light; when an obstacle is present, the light reflects back to the receiver, triggering a digital output signal on the OUT pin. The detection sensitivity can be adjusted using the on-board potentiometer.

Q: Can I use this sensor module with a smart car robot kit?

A: Yes! This IR infrared sensor module is specifically designed for smart car robot applications. Its 3-wire interface (VCC, GND, OUT) plugs directly into most Arduino-based robot chassis and smart car kits, enabling automatic obstacle detection and avoidance behavior.
