Sometimes those changes can be caused by light being blinked on and off by the wind moving leaves or tree branches etc back and forth across a warm source.
Can wind trigger motion lights. Turn off the switch which operates the motion sensor light. Perhaps I can try duct tape over halfpart of the snsor but since it only happens when its windy and even then its pretty inconsistent maybe once. That is after all the purpose of having a motion detector light.
Ive made sure the sensors arent pointing in the direction of any leafy trees that may be setting it off. I did this to a couple iris motion sensors to trigger only when I walk updown my stairs. Need to figure out the triggers to turn off though if.
Thatll trigger them as cold plants in front of a warm building is seen as movement of heat You can blinker the sensor with insulation tape to restrict its field of vision if this would help. Keep the switch off for 1 to 2 seconds and then turn the light switch on again. If the light or sensor sways in the wind that might trigger a motion event.
Pets vermin fax mailbox radiator or boiler etc. So if you want to have an emitter that will trigger the PIR make a temperature controlled emitter run it at 100 C to be safe and it will emit a lot more light in the 10 - 14µm band than a body temperature device. A motion sensor light is attached to a motion sensor.
You can also decrease the field of view on some sensors. If your motion detector lights are activated by heat your air conditioning and. 1 Sudden infrared movement heat changes in view of the detector.
They can also be triggered by sunlight campfires or distant IR light sources etc. In difficult environments strong wind blowing leaves on trees or similar objects can trigger the motion sensor. Check the area for any other lighting sources.
