Using a button on the key-fob remote control, activate the alarm under the seat from up to 100 feet away. Now, if anyone jostles the bike, a piercing alarm sounds.

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!

It’s compatible with the Arduino IDE and also contains a USB port for easy programming. The Trinket is hooked up to a GY-521 accelerometer, which allows it to detect motion.

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.

arduino gsm security alarm Working of the system is very simple and self-explanatory. When input power is applied to the system, the system goes into standby mode. However, when the terminals of ...

All you need is an Arduino, a motion sensor, a few wires and headers, and the code provided at the site below. Hit the link to see step-by-step instructions on how to put it together.

If you have an upcoming long distance move and you're concerned about thieves breaking into your moving truck you can rig up a motion alarm system that will send a text message as well as trigger ...

And should your square-footage be much larger, you can go up to $330 for a 14-piece set that includes two keypads, eight contact sensors and two motion detectors.

This Arduino Mega attaches to a control box mounted near the front door that’s loaded up with an LCD, an NFC and RFID reader, and a few buttons to arm and disarm the system.

In addition to monitoring your home’s activity with door sensors and motion detection, many home security systems also support cameras, either inside or outside your home.
