Recently, I exhausted my stock of common passive infrared (PIR) motion sensor modules and was looking for a new one to play with. I searched the web for a small type with self-contained electronics.

ICP DAS USA releases PIR-130-DC, a 1-channel passive infrared (PIR) sensor module that detects human-body generated infrared waves within a range of approximately 8 meters (315 inches) in diameter ...

[ladyada] has a freshly-published and amazingly thorough tutorial on passive infrared (PIR) motion sensors. Most often seen in security floodlights and automatic doors, in creative hands these sensors ...

Detecting and measuring movement is an essential element for many industrial and commercial IoT applications – from lighting and security to assisted driving. Motion detection systems consist of a ...

In the microcontroller era today, Arduino is more than just a tool to accomplish hobby tasks. There is actually a close relationship between microcontroller technology and home security, since you can ...

STMicroelectronics is launching a human-presence and -motion detector to enhance security systems, home-automation equipment, and IoT devices that typically use passive infrared (PIR) sensing. The ...

Tempe, Arizona - Southwest Microwave, a leading global supplier of perimeter intrusion detection systems, has announced the introduction of the advanced Model 420 Passive Infrared (PIR) Sensor for ...

Unlike infrared optical sensors that use an LED transmitter and IR receiver, the PIR emits nothing. As its “passive” name suggests, it responds only to infrared energy radiated by the object being ...

As radar technology continues to advance, it offers an increasingly broad range of capabilities, making it a viable alternative to traditional passive infrared (PIR) sensors. With radar’s enhanced ...
