Sometimes we do not know if someone has entered our house, whether it is a thief or not even though we are in the house. for that I made a smart application where when someone enters the house, then there will be a notification on my cell phone that someone has entered the house and recorded the date and time.
1. Pir Sensor
I use a PIR sensor to detect human motion, where I place the sensor in the family room. when someone enters this sensor will detect movement and will send a high signal to Arduino.
2. Arduino Uno Rev 3
Arduino uno used to program input from the PIR sensor and sent to mobile phone
3. Bluetooth HC-05
Communication tool between arduino and mobile application.
When pir sensor detect motion, mobile phone will have notification and show where is position of motion and also date time, and it will saved.
