[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 sens… ...

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.

As indicated, our system requires a “Logic High (H)” level input to wake up. The best sensor you can use to detect an intrusion is the Passive Infrared (PIR) Sensor. The PIR Sensor detects the motion ...

Passive InfraRed sensors (PIRs) are electronic devices which are used in some security alarm systems to detect motion of an infrared emitting source, usually a human body.

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 ...

Components Electromechanical PIR-Sensor Interface IC Controls Any AC Load Oct. 8, 2008 The LS6506R is a pyroelectric infrared (PIR) sensor interface IC that is designed to drive a latching relay.

But if you’ve got a project that could benefit from the pairing of a powerful WiFi-enabled microcontroller and a passive infrared (PIR) motion sensor, the Bee Motion created by [Paul Price] is ...
