FAQ
1.Can PIR sensor detect cars?
PIR-based Motion Detection: In this case motion is detected by means of a PIR sensor, a passive infrared sensor. This sensor detects emitted infrared energy from objects (humans and animals, but also cars) in the form of heat.
2.Do PIR sensors work in the dark?
Yes, motion sensors work in the dark. The way that a motion sensor detects 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.
