Arduino with PIR Motion Sensor- that can detect movement. simple circuit with an Arduino and PIR motion sensor that can detect movement. An LED will light up when movement is detected.

The objective of this experiment is to use a PIR motion sensor to control a fan as a on/off switch. The PIR sensor will be used to detect if there is someone in front of the fan where then the raw ...

Here is an ultra simple Arduino Night Alarm project wired around a handful of inexpensive and easily available components. One advantage of using Arduino as a security system is the flexibility!

A number of technologies are available to design automatic door openers like PIR sensors, Radar sensors, Laser sensors, Infrared sensors, etc. In this arduino based project, we have tried to replicate ...

Even though Attiny85 is fitting here, I opted for Digispark just because of its plethora of features like USB programming interface, on-board voltage regulator, and Arduino IDE compatibility. The code ...

For his sensor, [Felix] is using a Moteino, a very tiny Arduino compatible board with solder pads for an RFM12B and RFM69 radio transceivers. These very inexpensive radios – about $4 each ...

RCWL 0516 Module The RCWL-0516 Microwave Radar Sensor module has been designed as an alternative to the common PIR motion sensors widely used in burglar alarms and security lights. Like the PIR Sensor ...

Present consists of just a PIR sensor and Arduino in a 3D printed enclosure to snap onto your monitor.
