4pins Digital Smart Pyroelectric Detector BS412
Overview of pyroelectric motion sensor
BS412 is a newest smart digital motion detector with a small window size. It offers a complete motion detector solution, with all electronic circuitry built into the detector housing. Only a power supply and power-switching components need to be added to make the entire motion switch.
BS412 includes the time setting only.
Features of pyroelectric ir detector
Built-in filter, screen the interference by other frequency
Excellent power supply rejection, Insensitive to RF interference
Applications of pyroelectronic 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
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.
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.
