Where to Place Your Sensor for the Best Results

Placement is the most common reason a sensor fails to perform as expected. Avoid placing motion sensors directly across from windows, as sudden changes in light or shadows can trigger false detections. Similarly, place sensors away from heating or cooling vents, as the rapid shift in temperature can confuse some infrared sensors.

For the best results, mount the sensor where it has a clear line of sight to the entry points of the room. Test the sensitivity before permanently securing the faceplate to ensure the light activates exactly when you reach the desired threshold. Proper placement prevents the frustration of lights staying on too long or not turning on at all.

• Pro-Tip: Always verify the sensor’s range and field of view provided on the packaging.
• Maintenance: Periodically wipe the sensor lens with a soft, dry cloth to prevent dust from obstructing the infrared signal.

Automatic lighting is a modest investment that yields significant dividends in both convenience and long-term energy savings. By choosing the right tool for the specific needs of your household, you ensure a smoother routine from the moment you step through the door. A well-lit home is not only more efficient but inherently more welcoming for everyone who resides there.
