This motion detector alarm can detect a moving person from a distance of 1 meter. It uses a dual IR Transmitter-Receiver module HOA1405. When the sensor detects the reflected IR rays, alarm will sound ...

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 ...

A motion sensor ensures that the lights are only on when there are people around to actually see the lights. The circuit also has an adjustable timer so [brmarcum] can change the length of time ...

Philips Hue has a new accessory that’ll make it even easier to automate the lighting in your home: a motion sensor. This is, of course, a very standard add-on for home lighting — which is what ...

Using motion detectors and an Ardunio you can add a little extra wow to your Halloween displays this year. This article covers the circuits and the code to make that happen.

Drill the new outdoor motion light into your target location. Turn the power back on at the circuit breaker panel. Calibrate your motion detector to the correct angle and sensitivity.

In the previous article we covered [connor] demonstrating the motion detector. Something about the way the ADC circuit for the Arduino is wired up makes it work.

A Philips Hue motion detector may soon be a reality, according to a new FCC filing spotted by Dave Zatz. Instead of having to deal with a second smart home system like SmartThings to get a proper ...

Windows only: Motion Detection is a free application that turns your webcam into a motion-sensing security camera in just a few clicks. Assuming you've got a webcam hooked up to your computer, all ...

Motion-sensitive neurons have long been studied in both the mammalian retina and the insect optic lobe, yet striking similarities have become obvious only recently. Detailed studies at the circuit ...
