The mini PIR motion was used to implement an automatic staircase lighting and is doing really well. There were 2 PIR detectors (1 * for the staircase, 1 * stairway) fitted, switch the stair lighting (LED light bars). Unfortunately, the light sensitivity as already other described a little too insensitive so that one but some switch tripping has where they are not needed, but these are each 12 LED strips with a consumption of 12 watts for a period of one minute, the is yet to be absorbed.
Update: 09/2014 What a shame, but unfortunately both PIR motion detector are defective. Either turn off by itself, does not turn or turn and no longer made. Have they now face completely different, (expensive GEV Mini recessed motion detector 360 ° LBD 1251) replaced because me then with continuous illumination the matter but was too stupid. Schade was actually on the size and the type (and the price) ideal.
