    • Dual LED indicators provide real-time feedback without requiring external monitoring.
    • IP67 rating ensures the Pro Model withstands harsh outdoor environments, exceeding standard PIR sensor durability.

  2. Version Selection Guide:

    • Base Model: Ideal for hobbyists and educational projects requiring basic motion detection (e.g., classroom robotics).
    • Advanced Model: Suited for home automation (e.g., smart lighting) where adjustable sensitivity and low power are priorities.
    • Pro Model: Best for industrial or outdoor applications (e.g., warehouse security) needing extended range and weather resistance.

With the Pro Model’s 6.5m detection range, you can monitor larger areas than traditional sensors. Pair its IP67 rating with rugged materials to ensure reliability in rain or dust. The Advanced Model’s adjustable sensitivity makes it perfect for balancing precision and power efficiency in smart homes.
