Works OK. Sensitivity isn't very good, you need to wave your arms in the area for 2-3s for detection. Distance working is about 4m not 7m. Angle of detection is really 90deg or less. If you plan to use to turn on lights in your hallway, you will walk at normal speed and reach right under the sensor before it triggers.
