PIR Motion Sensor Motion sensing is useful for a range of applications, from intruder detection to home automation. PIR motion sensors use infrared light to detect movement.

I recently had to build an infrared close proximity sensor that could tell if something was dropped in a parcel delivery drop box. After some searching, I ended up using a microcontroller and a piece ...

Makers and developers looking for a motion sensor Arduino Shield, ... In addition, this shield has an on-board Infra-red (IR) sensor that can pick up signals from a 38kHz remote control, ...

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. Aspencore network. ... Following is the ...

[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… ...

When everything’s plugged in, this is how your Arduino, motion sensor, and power relay should look. Jeremy S. Cook Plug the male-to-female jumper wires into the motion sensor pins.

Passive infrared (PIR) sensors detect infrared energy radiating from objects within their field of vision. Resources; ... Sensor Sense: Passive Infrared-Motion Sensors. July 10, 2008.

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.
