Rosacea - Symptoms. Rosacea causes a range of symptoms, although not everyone will experience them all. Most people with rosacea have periods when their symptoms are particularly troublesome, followed by periods when their symptoms are less so.
Most motion detectors have a built-in override: 1  Normally the switch is kept on all the time. 2  If you turn the switch off and on within a second or so, the light will stay on, and this overrides motion detection. 3  To go back to normal operation, turn the switch off and wait ~10 seconds, then turn back on.
If the motion detector is located in front of your garage and you want it to turn on every time you drive up the driveway, but not when cars drive by on the street, tilt the sensor down a little bit so that it detects motion in the driveway but not on the road.
