To activate your IR sensor, typically you need to bring an object into its detection range. Here's a simple explanation:
- Initial Activation: Bring your hand or any object in front of the sensor. In doing so, the signal LED should turn ON. This indicates the sensor is detecting an object.
- Calibration (If needed): If the signal LED does not turn on when an object is in front of the sensor, the sensor might need calibration. Refer to the manufacturer's instructions for the specific calibration process for your IR sensor model.
In essence, the IR sensor "turns on" when it detects infrared light being reflected back from an object within its range. The sensor itself is always powered (assuming it's connected to a power source), but its output signal changes when it detects something.
