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!

Components used in this project: 1x Arduino 101 3x Jumper wire 1x PIR sensor 1x LED light 1x USB cable Background: Arduino 101 is a microcontroller which can take in inputs and produce an output. In ...

PIR sensors are more complicated than many of the other sensors explained in these tutorials (like photocells, FSRs and tilt switches) because there are multiple variables that affect the sensors ...

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

The PIR module actually consists of a pyroelectric sensor (looks like an old metal transistor with a black window on the top), which generates energy when exposed to heat, and it’s tied in closely ...

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

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 ...

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 ...
