The red light blinking on your device's motion sensor indicates that it is detecting movement or activity in its vicinity.
Is PIR a common device used for detecting motion indoors on a security alarm system?
Yes it is, a PIR stands for Passive InfraRed, which detects heat signatures. For a higher level of security, I would recommend dual band motion detectors with PIR and Microwave Detection capability.
What does an accelerometer measure and how does it work?
An accelerometer measures acceleration, which is the rate of change of velocity. It works by detecting changes in motion through the use of sensors that respond to forces acting on the device.
What is the purpose of the motion tracker in the movie aliens?

What is a device that changes linear motion into circular motion?
A rack and pinion system is a simple mechanism which converts linear to circular motion. More complex systems such as the pistons of a car engine rotating the drive shaft are common.
What are the 3 pointing devices and their illustration?
The 3 common pointing devices are the mouse, trackpad, and stylus. A mouse is a handheld device that moves a cursor on a screen by detecting motion. A trackpad is a touch-sensitive pad on laptops that functions like a mouse. A stylus is a pen-like tool used on touchscreens for more precise input than fingers.
