Webb27 jan. 2024 · In normal conditions, wind alone can’t set off the motion detector. Air doesn’t have an infrared heat signature, so the PIR won’t capture any movement with the wind blowing past. And basic movement sensors are based on light, so don’t see the invisible air particles’ movement. So, if your security light switches on during wind, you ... WebbThe PIR sensor is suitable for working at the frequency from 0.1 to 100 Hz.7 Usually the response of the device almost has a slope of 220 dB/decade for frequencies higher than 1 Hz. Because the PIR sensor responds to the rate of change of temperature dT/dt, it is suitable to measure pulse-type radiation power.

WebbThese sensors use a PIR sensor, with a much narrower field of view, of course, than PIR motion sensors. It will not only detect IR radiation, it will also register the intensity of that IR radiation. By comparing it to established baselines using some fancy algorithmic tools, it can translate that intensity to a numeric temperature. Neat!
