A motion sensor bulb is designed to automatically illuminate when it detects movement, offering hands-free convenience and energy savings by turning off when no motion is present. A radar bulb utilizes microwave sensing technology to detect motion with greater precision, even through walls and objects, ensuring a wider and more responsive detection area. The Smart Bulb by ESYSENSE integrates advanced radar motion detection with smart lighting features, providing efficient, adaptive illumination for enhanced security, comfort, and automation in any space.
