Here is one simple circuit of a general-purpose white LED security light with Passive Infrared (PIR) Motion sensing mechanism. At the heart of the circuit is a PIR sensor module SB0061. SB0061 is a ...

SwitchBot has announced a new product called the Presence Sensor with mmWave Radar. This sensor is built to detect people in ...

Module provides integration and flexibility for passive infrared (PIR)-based motion detection applications including customer sensing, lighting control and other energy management purposes. The ...

There’s no shortage of ESP32 development boards out there, with many of them offering some “killer app” feature which may or may not align with whatever it is you’re trying to do. But if you’ve got a ...

(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 ...

Security lighting is widely used as a preventive measure against intrusions on a physical piece of property. Since adequate lighting around a physical structure reduces the risk of an intrusion, ...

Many close-proximity motion detectors use the classic, widely available passive-infrared (PIR) approach, which is effective but has limited sensitivity and adjustability, and can’t “see” through ...
