Most can detect movement ten feet away, however some can detect twenty or thirty feet.
a light sensor is movement is made this triggers off the sensor which turns of the light

Because motion sensors sense the movement of light, so if its dark, it cant see.
this depends on the situation. normally all one would need is a thermal sensor in order to detect light
detector is only signal the pressure and sensor both signal the pressure and stimuli
An optical mouse functions by using a laser light sensor to detect movement of the mouse instead of a roller ball. An optical mouse can be wired or wireless.
It Is A Sensor That Detect Light So If Its Dark Your Screen Monitor Brightness Will dim down so you're not looking at one source of extreme bright light, When Its Bright The Screen Monitor Will go up to compensate for the extra light around you so you can still see the monitor comfortably
Something that senses light, movement or sound
it detects any movement if anything passes it Ex: if you pass a motioin sensor light the light will come on
