The Etch a Sketch toy has gone more or less unchanged for over 60 years, but if you’re handy with a soldering iron you can build an upgraded version that ...

It’s a fairly simple project, too: just hook an Arduino Uno up to a motion sensor and an electronic switch called a relay, then plug in your fan, and you’re good to go.

Researchers designed an IoT network using sound and motion sensors that estimates public space utilization. The ideas can be applied to other IoT sensor networks.

Passive IR (PIR) sensor modules provide motion detection and control to smart home and building systems.

Espressif has many different types of ESP32 devices, and while "ESP32" is used as a general expression to refer to the line ...

So CNET's Associate Technical Editor Steve Conaway and I decided to build a flood sensor that could cover a whole room, and we figured out you can do it for under five bucks.

A passive infrared motion sensor is used to detect the motion of the user’s hand in front of the clock. While all kinds of clocks and clock radios are available out there, few are motion activated.

Kano’s Motion Sensor Kit is a USB-pluggable sensor that detects direction and distance with infrared. You hook it up to Kano Code to make interactive games, musical instruments, or whatever else ...

If you can install a conventional outdoor light fixture, you can install a motion sensor light, although aiming and adjusting it takes extra effort.

The Eve motion sensor lets you create automations to trigger lights and other HomeKit devices based on when someone is in in the room.

The Onvis Motion Sensor tracks room motion to enable HomeKit light automations as well as track temperature and humidity.
