In this security system is based on the embedded system along with GSM and sensor networks. The human movement is detected using the PIR sensors.
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!
These sensor nodes are physically connected using Arduino Mega Board. If intrusion is detected, the Arduino Mega Board generates an alert notification and sends it to the 3G/GPRS Shield (SIM5215A) ...
Smart-Security-System-using-PIR A simple and effective motion detection security system built using an Arduino, a PIR sensor, and a buzzer/LED. When motion is detected, the system triggers an alert, ...
