The MS600 uses a combination of the super-precise radar tech, PIR, and light sensors to detect small movements, such as breathing, as well as general motion and light levels. The sizeable sensor ...

(Passive InfraRed sensor) A device used to detect motion by receiving infrared radiation. When a person walks past the sensor, it detects a rapid change of infrared energy and sends a signal. PIR ...

PIR sensors (PIRs) use heat radiation from bodies to identify the presence of people and animals. This can be used for unlocking doors or starting a video recording.

Moreover, radar sensors can be combined with optical cameras, using radar as a long-distance trigger to activate camera functionality. The high-precision mmWave radar offers a host of advantages over ...

In this security system is based on the embedded system along with GSM and sensor networks. The human movement is detected using the PIR sensors.

PIR sensors made by Panasonic (PaPIRs) use Lithium Tantalate (LiTa03), and are lead (Pb) free under the terms of the European RoHS (Restriction of Hazardous Substances) Directive.
