Microve Sensor question

[C.C.SHACKLETON]

Hiya Gents. First post so please easy does it!

Has anyone ever masked part of a microwave sensor to prevent nuisance triggering?
What is suitable material?
Thanks Phill.

The ones I have had dealings (early 90's) with had a sensitivity switch (h,m&l)inside plus a potentiometer for fine tuning for that very same purpose. I don't think these could be masked as such.

Hello and thanks,I've tried cranking it down to MIN but then the range is poor and defeats the object.
It is mounted outside, location was limited and passing buses set it off.

It was a freeby.....at my age I should have known better!!!

I would expect that using say the self adhesive aluminium tape would mask the microwaves as they will be blocked by metal, possibly sticking a small section of aluminium foil may also work.

Thanks Richard...will try at the weekend and report back.

What kind of microwave sensor do you have and wha's the application?

Thanks for the interest,I'ts a Knightsbridge/ML Accessories unit from my usual indy lighting man (don't laugh all the
bigboys in Bristol use him!)

I,ve put it in a Fern Howard 28W adapted to run an LED Retro-Fit in my back garden in an attempt to dissuade the
local NEDS from visiting.Trouble is it picks up all sorts of false triggers due to its inherent efficiency.

Trouble is I'm an old school 3/4" conduit/7.029/ 268 PYRO Fart and I won't let It best me!!!!

Infra red sensors can be masked, but micro wave dropplers are going to be tricky......possible aluminium foil, but its going to be test it and see
