You can use mmWave sensors to monitor presence rather than simply detecting motion.

It’s really hard to overstate how awesome ESP8266 development boards like the Wemos D1 Mini really are. For literally a couple of dollars you can get a decently powerful Wi-Fi enabled microcontroller ...

The presented schematic shows how to build a simple PIR motion sensor. PIR sensors allow motion sensing, it is almost always used to detect whether someone has moved in or out of the sensors range.

Kangaroo’s latest motion sensor adds entry detection to the mix, but its lack of geofencing capabilities or support for any type of security camera makes it tough to recommend. It’s one thing to snap ...

Your garden variety motion detector uses IR, but these days, there are fancier technologies for achieving similar goals. If so desired, you can source yourself a microwave-based presence sensor ...

“These are, by far, the best solar lights I’ve ever owned.” ...

The Hue Outdoor Sensor is the first outdoor HomeKit sensor, and adds motion, temperature, and light sensors to automate the outside of your Apple-centric smart home. Recently, we took a look at the ...

As radar technology continues to advance, it offers an increasingly broad range of capabilities, making it a viable alternative to traditional passive infrared (PIR) sensors. With radar’s enhanced ...
