Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

The Aqara FP300 is a battery-powered presence sensor with Thread and mmWave radar, giving HomeKit precise motion and ...

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 ...

Motion detection is the magic ingredient in the current wave of do-it-yourself home security cameras. Thanks to built-in sensors that vigilantly monitor their field of view for movement, you can go ...

It’s really hard to overstate how awesome ESP8266 development boards like the Wemos D1 Mini really are. For literally a couple of dollars you can get a decently powerful Wi-Fi enabled microcontroller ...

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 ...

TAKEX PIR-T40NAM is an indoor/outdoor 135 feet/40 meter long range vertical curtain passive infrared utilizing triple mirror technology and signal processing for accurate detection and small animal ...

Need a cheap and easy way to deter intruders? For homeowners, outdoor lighting is a game changer for providing a line of sight on potential trepassers without running up costly energy bills. If you're ...
