Philio PHL-DWMLT-PSM02-US

With this one compact device, sense door/window opening/closing, motion, light, and temperature. Mount the PSM02 on any door or window in your home or business, and like all door/window sensors it will alert your system when the small magnet separates from the sensor, indicating an open door or window. What makes this sensor unusual, and very convenient, is that it will also tell your Vera system the temperature, the ambient light level, and best of all, whether motion is detected in the vicinity of the door or window. You can use the muli-function sensor as a remote temperature sensor to control A/C or heating. Use it as an ambient light sensor to automatically turn on room lights at night.
