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 ...

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.

Geneva, Switzerland, July 24, 2023 – STMicroelectronics, a global semiconductor leader serving customers across the spectrum of electronics applications, is launching a novel human-presence and ...

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 ...

The motion sensor was designed using a pyroelectric sensor which is essentially a FET with a window in the case opening onto an infrared-sensitive gate. The circuit is monitoring the changes in the ...
