Applications of BS412 Pyroelectric Infrared Sensor
home security systems
As its ability to sense warm, moving objects such as people walking into a room is coupled with simplicity and cost effectiveness.
FAQ of Pyroelectric Sensor
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.
- pyroelectric sensor workingin 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.
