This sensor is a little bit better, but still not perfect.
He recognizes me at the highest level in about 1.5 meters.
I turn the thing around and use it in a hanging lamp, he knows me well over 4 meters.
The twilight switch is working very well, so I'm using it as a twilight switch, because as a motion he still has a drawback. The light attracts the night of the insects and activate the sensor, ie, the lights all night, except I turn back the sensitivity, then he does not recognize me anymore.
Buy Once again, I would not, but then there is also nothing better to shop here at the price,
So I use them with energy-saving lamps (one should because of the many circuits net, but as I said, in my burns through the night)
