Arduino leak sensors only have three pins to connect, ... PIR Motion Sensor . Motion sensing is useful for a range of applications, from intruder detection to home automation.

When everything’s plugged in, this is how your Arduino, motion sensor, and power relay should look. Jeremy S. Cook. Plug the male-to-female jumper wires into the motion sensor pins.

Using motion detectors and an Arduino you can trigger lights, ... The PIR Motion Sensor on the left is made by Parallax and sold by Radio Shack. The one on the right comes from Sparkfun.

If you've always wanted to try to build an Arduino project, this may be a great way to start. Matt Williamson built a tiny, Arduino-based motion sensor that will SMS you when something moves by ...

That’s right, these parking sensors are powered by an Arduino board, and the only extra components that were used in the project are a HC SR04 ultrasonic sensor, an active buzzer, and jumper wires.

You'll definitely need some gear for it—the Arduino for one, but also a PIR motion sensor, not to mention the (cleaned and rinsed!) Raid Power Sprayer motorized spray bottle.

The Leap Motion controller is a rather impressive little sensor bar that is capable of generating a massive 3D point cloud and recognizing hands and fingers to allow for gesture control based compu… ...

Somehow 2.4Ghz wifi from esp8266 is triggering motion sensor. I tried shielding sensor with aluminium foil, adding capacitors… nothing helped. I googled and found that I’m not the only one.
