The project aims in designing a Smart home automation and smart security system using Raspberry pi. The project makes a use of raspberry pi zero W processor which has an inbuilt WI-FI and which is used for sending the alert mail along with photos. This project consists of Bluetooth technology for controlling the devices wirelessly from android Bluetooth mobile application.   The controlling device of the whole system is a raspberry pi zero W processor. LCD display, Pi-camera, servo Motor, Bluetooth module, PIR, Buzzer, keypad, GSM and relay along with bulb and transistor with fan is interfaced to the raspberry pi processor. After the system detects the motion using PIR, when the person does not enter the PIN within a certain time, Raspberry pi will send an alert SMS through GSM and also sending alert MAIL along with photo to the predefine stored email. When the person enters the PIN with in the time, it will send the OTP to the user. So, user need to send the OTP through keypad with in the time. When the raspberry pi detects a wrong OTP or PIN, Raspberry pi will capture the person image and mails it. If the entered OTP matches the generated OTP, then the system accesses the door and lets the person in. This device consists of Bluetooth technology for controlling the devices through voice from android mobile application. Based on the received commands, raspberry pi will turn ON/OFF the devices accordingly. The main controlling device of the project is Raspberry Pi. We program it using Python Language and the OS used here is Linux.

 

The major features of this project are:

• Buzzer, mail and SMS alert for unknown persons.
• PIR sensor-based motion detection.
• Using Pi camera to capture the image.
• GSM based SMS and OTP sending system.
• Servo motor-based door lock/unlock.
• Using raspberry pi ZERO W to achieve this task.
• Voice Based Home automation using Bluetooth technology.
• To achieve this task using RASPBERRY pi zero W processor.

The major building blocks of this project are:

• Power Supply.
• Raspberry pi ZERO W.
• SD card.
• Pi camera.
