Frequently Asked Questions

What is the operating voltage range for this sensor?

The sensor is designed to operate strictly at 5V DC. Exceeding this voltage may damage the internal components. Ensure your power supply provides a stable 5V output, typically from an Arduino 5V pin or a regulated USB power source.

How do I adjust the detection range?

Use a small screwdriver to turn the potentiometer screw located on the back of the sensor module. Clockwise rotation typically increases the detection range/sensitivity, while counter-clockwise rotation decreases it. Adjust while testing with a target object at your desired detection distance.

How do I connect and read the sensor output with an Arduino?

Connect the sensor's Gravity cable: Brown wire to 5V, Black wire to a digital input pin (e.g., D2), and Blue wire to GND. In your Arduino sketch, configure the chosen pin as an INPUT and use `digitalRead()` to monitor its state. The pin will read LOW when an object is detected within the set range.

Is this sensor suitable for outdoor use?

No, it is primarily designed for indoor applications. Direct sunlight and highly reflective outdoor surfaces can interfere with the infrared signal, causing unreliable readings or false triggers. For outdoor proximity sensing, consider ultrasonic or LiDAR-based sensors.

What is the purpose of the red LED on the sensor?

The red LED serves as a status indicator. It lights up when the sensor is powered on. Its behavior may also change (e.g., dimming or flashing) to indicate detection events, providing immediate visual feedback during setup and debugging without requiring serial monitor output.
