It is likely that many of us will at some time have experimented with motion detectors. Our Arduinos, Raspberry Pis, Beaglebones or whatever will have been hooked up to ultrasonic or PIR boards whi… ...

TK has combined a PIR with an Arduino to create a smart safety light for the house or workshop. Follow along as this gets built out into a more extensive project.

DWEII 12PCS RCWL-0516 Motion Detection Sensor, Microwave Radar Sensor, Switch Module, for Arduino ESP8266 Nodemcu Wemos, for Raspberry PI, for Human Rat Cat Detector, Detection Distance 5-7m DWEII ...

The accelerometer uses sensors to detect the motion and speed of your hand, while the connected Arduino board will pick up on your motions and work out the commands.

The project’s goal — in excess of a lighting solution for an entrance hallway — was the learn the ins and outs of the Arduino and motion sensors.

I've just come across a no-name non-contact, high-precision 80 GHz mmWave radar sensor for liquid level detection with a 40m ...

Make sure the adjustment knobs for sensitivity and on-time for the motion sensor are facing up so you can modify how sensitive your device is and how long it stays on to signal your Arduino.

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 ...
