an intelligent home entry system
It allows the user to grant entry to any visitor to his house remotely after viewing the visitor spicture. A cellphone supporting a camera and mms functionality is to be used with our device.The main processor is a pic microcontroller that is connected to a doorbell and an electronic lock. This whole assembly is mounted on the door. The user is required to connect a cell phone with this microcontroller using a usb data cable
Methodology
When a visitor presses the door bell, the microcontroller will signal the cell phone to take a picture of the person and send this as an mms to the user s cell phone. The user can then review this mms using our application and then decide if the door is to be opened or not. The response is sent back to the device as a sms. The microcontroller then interprets this and opens the door.Major Components
1. Microcontroller:
We will be using Pic24f series microcontroller development board and MPLAB
IDE for microcontroller coding and compilation.
For our Project we require pic to send data to mobile using USB which require
a USB host. Only pic 24f and above family have this feature.
2. Java Application:
Developed using J2ME/MIDP 2.0. We have decided to develop the app in Java
because of Java s inherent platform independence. Therefore, the user can use
any modern cellphone supporting java.
3. Electronic lock
4. Electronic door bell
