FAQ
D203B datasheetcan detect up to distances of 8- 10M.
- How passive infrared sensors work
Yes, motion sensors work in the dark. The way that a dual pir sensordetects movement has nothing to do with how light or dark it is in the immediate area. ... Since infrared energy is present and can be detected regardless of the amount of light in the environment, a PIR motion sensor will work just fine in the dark.
