hi reflectees!
i had sensor lamp problems right in my home. The only cure i found for
them is using E-Type ferrite chokes.
The chokes avoid the internal oscillator energy being fed into the
mains, plus they avoid the triggering of the internal switch.
I used SIEMENS N27 type E-cores, they are about 4 inches on a side. The
functionality of the lamps is not affected whatsoever. Nor do You have
to cut any wires, just coil them up in the double E-core.
It works from DC to daylight, so to speak. No other commercially
available L and C configuration filters gave the immunity to RF that i
achieved with the choke.
