This time I have made Home Security System , I named it AEGIS. The home security is vulnerable nowadays so this project is one step forward for our home security. This system is distributed in two units Front door and Rear door both are connected via bluetooth. Main unit is connected to GSM. If burglar detects i will get notified via CALL .

Step 1: Components
For this project I have used
- HC-05 bluetooth
- Arduino uno and nano
- GSM module SIM-300
- 12v adapter
- Relay module
- 5v adapter
- PIR sensor
Step 2: Front Door and Rear Door Module
The silver aluminium case is my front door module and red one is rear door module.The pith of this project is front door module .It consists of GSM module,Arduino nano,Relay ,Bluetooth. The bluetooth here in this unit is master and connected to slave (rear door unit) by 1 to 1 connection . There are total 3 leds. One is power led ,second is ARM led and third is Trigger led.I have given 1 minute of starting delay to calibrate the PIR sensor. In between this time period arm led will blink and after that it will get stable. Whenever human detects i will get notify by CALL and trigger led will glow.
Step 3: PIR SENSOR
This pir sensors are working on pyroelectric method .It detects heat from the human or animal body and get triggered.The sensitivity of sensor can be changed by tripod , I have used this sensor around 35-40 % sensitivity and in L mode with minimum time delay.
*YOU WILL REQUIRED 2-3 FOR TRIAL AND ERROR METHOD TO DETERMINE THE SENSITIVITY OF SENSOR ,BECAUSE SUN LIGHT AND ARTIFICIAL LIGHT WILL AFFECT THE SENSOR AND SOME TIME IT WILL GET TRIGGERED
* MY SENSOR WAS GIVING HIGH SIGNAL WHENEVER IT DETECTS THE HUMAN ,THERE ARE MANY LOW TYPE SENSOR WHICH GIVES LOW SIGNAL WHEN IT DE
