The SP816 Outdoor Motion Detector is a Z-Wave PlusTM enabled device and is fully compatible with any Z-WaveTM enabled network. The device can be set up in a Z-Wave network to communicate directly with other end devices such as lighting controllers, or to report directly to a Z-Eave controller (usually a gateway). This motion detector is primarily designed for outdoor lighting control application. It features a PIR motion detector to detect movement in a protected area and a lux sensor for determining brightness of its surroundings. It comes with a built in timer to set the duration for light turn on. The lux level and the timer can be set through knobs on the device itself. If the PIR detects motion when lux level falls below a preset setting, the device will transmit a signal to turn on the outdoor lighting (or indirectly through gateway) and then later turns it off when its timer has elapsed. This device can also be used as a basic motion sensor for indoor security application.
