Security systems is one of the most researched fields of today. Through this project, you will develop an electronic device that can detect the human activity and switch on the buzzer to alert the user. The system will also be connected to the internet and can send the data to the cloud spontaneously.
You will need an Arduino Uno board to act as the brain of the system. And the microcontroller will be connected with a WiFi module to establish an internet connection. The smart device that you build will have PIR (Passive Infra-Red) sensors that detects the human activities over a particular range.
You will program the microcontroller in such a way that say whenever a human activity is detected by the PIR sensors, the buzzer will switch on automatically and alert the residents regarding this. You can also innovate the system further to send a notification to a user at any part of the world via sms or email.
In this system a two-way communication is established between the mobile user and the visitor. Like the user can know the visitor’s motion from any remote location and also secures the home from strangers and intruders. The user mobile will also include options for viewing the motion of the visitors, turning ON and OFF the electronic devices in home at particular time, activating the alarm systems etc.
Arduino Uno: The digital and analog input/output pins are equipped in boards that may be interfaced to various expansion boards and other circuits. Serial communication interface is a feature in this board, including USB which will be used to load the programs from computer.
Voltage regulator: It is used to maintain a constant voltage level and also used for regulating AC or DC voltages. A voltage regulator contain negative feed-forward design or it may also contain negative feedback control loops.
WiFi Module: ESP8266 WiFi module is generally used to establish the wireless communication between the devices. But this module is not capable of 5-3V logic shifting and will require an external logic level converter.
PIR Sensor: It is capable of sensing motion of the human and therefore it is also called as a motion sensor. Whenever a human pass through this sensor it will automatically sense the motion through IR radiation and send the data to the microcontroller.
An application should be developed and installed in the mobile
ESP8266 WiFi module used for providing communication between the application and system
PIR sensor will sense the motion and send the data to the microcontroller to alert the user
Also the buzzer gets triggered whenever a motion is detected
All the data collected will be sent to the cloud (ThinkSpeak IOT platform) for storage and analysis
You will be needing Arduino IDE software to write and upload the programming logic onto the Arduino Uno board
Also, you need to create an account in the ThinkSpeak IoT platform to integrate the system onto the cloud and store the data online
Programming language: Arduino Programming (C++)
