P.I.R. Operated Outside Lights.

Zoomup

In the windy weather people complain about P.I.R. operated automatic outside lights constantly operating at night. What is the best way to “de-sensitise” them to prevent nuisance operation if they have no sensitivity control?

    Depends what's triggering them. Often it's trees/bushes blowing about in the wind that screen (or not) something of a different temperature behind them (e.g. a heated building) - fooling the PIR into seeing the changes in warmth they're meant to respond to. If movement infront of the trees/bushes isn't needed to trigger the lights then re-pointing the sensor to void the trees or masking part of the sensor with tape can help. Or cutting back the bushes, so they don't move so much.
