pir without lux adjust

[brizospark]

Does anyone know where I can buy a pir occupancy sensor that does not have lux adjustment and will work whatever level of light

Preferably ceiling flush mounted like a doenlight

if you set the lux to come on during the light (day time) it will still work at night (in the dark)

the lux is purely just to tell the unit what level of light it should operate with

I am aware of this but there is still a minimum level of darkness which has to be achieved before a lot of photocells will work even set at highest lux level

if in doubt, use an alarm PIR sensor to activate a contactor.

they work in all light conditions

This'll do the job:
Danlers PIR Occupancy Ceiling Switch - 6 Amps

If not use a pir from a fan manufacturer like vent Axia or something. They have no lux settings on them
