The light should come on automatically when it is dark and the motion detector detects a movement, e.g. in a corridor, staircase or garage? Then use the socket adapter with light and PIR sensor from LogiLink. Simply plug the PA0248 into the socket and the plug of the device to be switched on - such as a standard lamp - into the adapter. If the surrounding is dark enough (<5 Lux) and the PIR sensor detects movement (at a distance of up to 8m) within its 100° detection range, the socket is switched on.
