The presented schematic shows how to build a simple PIR motion sensor. PIR sensors allow motion sensing, it is almost always used to detect whether someone has moved in or out of the sensors range.

IR-7/IR-8 passive infrared motion detector is a microprocessor controlled PIR Detector. Its advanced digitalized adaptive signal processor algorithm enables the PIR detector to maintain a stable ...

IR-15 is super compact in design and yet has a wide detection angle of 160 degrees. It uses Lithium battery, thus ensuring longer battery life. Moreover, it is tamper-proof against opening of its ...

Geneva, Switzerland, July 24, 2023 – STMicroelectronics (NYSE: STM), a global semiconductor leader serving customers across the spectrum of electronics applications, is launching a novel ...

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 ...

Sandia National Laboratories optical engineer Michael Goldflam sets up equipment to load and characterize a new nanoantenna-enabled detector. A team of researchers at Sandia National Laboratories has ...

This infrared detector can be used to detect the presence of modulated infrared signals in its vicinity from any electronic source, for instance, an IR handheld remote controller. It can also be used ...
