The motion sensor switch circuit can automatically turn on a water sprinkler but you can easily use it as a motion sensor light switch or motion activated alarm too. Before beginning the construction ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

I've never actually had anyone try to run off with my laptop, but then again I usually don't leave it sitting somewhere while I wander off. For those of you that feel the urge to leave your precious ...

With cases of burglaries on the rise, CCTVs are no longer enough. While they do help in surveillance, they can’t alert you immediately in real-time. If you are looking for ways to kick your home ...

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 ...

With Hillcrest Labs' Freespace motion control technology embedded in handheld devices, consumers can operate CE equipment and use natural movements to navigate and select content on-screen with ...

What if you could take your temperature without a thermometer? Researchers at the University of Tokyo have developed a wearable device that can continuously monitor a patient’s temperature – and sound ...
