Another frequent problem is inconsistent activation, where the lights fail to turn on when someone approaches. This can be frustrating and is often due to:

• Obstructed View: If the sensor is blocked by objects or furniture, it may not detect motion properly.
• Low Battery: For battery-operated models, low battery levels can impact performance.
• Incorrect Sensor Settings: Settings such as sensitivity or timer duration may need adjustment.

To resolve this, ensure that the sensor has a clear line of sight, replace batteries if necessary, and review the settings to optimize performance.

3. Short Range Detection

Sometimes, LED motion sensors may have a limited detection range, which can be caused by:

• Environmental Factors: Walls, furniture, or landscaping can obstruct the sensor's field of view.
• Sensor Quality: Lower-quality sensors may inherently have a shorter detection range.
• Improper Mounting Height: Mounting the sensor too high or too low can affect its ability to detect motion.

To address this issue, evaluate the mounting height and location of the sensor, and consider upgrading to a higher-quality unit if necessary.

When to Replace Your LED Motion Sensor: Signs to Look For
