Android Controlled Remote AC Power Control

Android Controlled Remote Ac Power Control Project

AC Power Control System this project is to control AC power to load remotely with altering voltages applied to this to it with the help of Android application devices or smart phone.

The proposed system uses a AT89S52 micro-controller of the 8051 family and a rectifier power supply. In this system, the op-amp used as a comparator for finding zero crossing of the voltages.  In this system, the 230AC lamp is controlled by thyristors which are connected to the micro-controller with help of opto-isolator. The isolator is used for isolating the loads from the micro-controller control section. A Bluetooth module is connected to the micro-controller for communication.

The AC power is controlled by triggering Pulses from the micro-controller. The micro-controller receives the control signal from the Android application and set the desired output supply to switch thyristors to control the loads Supply.

Android Password Based Remote Door Opener System Project

Android Based Password Door Open System

Our project aims at remote password based door opener system through an android application. The system tends to make a secure door opening mechanism such that the door only unlocks when a security personnel opens it by entering the right password through an android application. The authorised person needs to be present within Bluetooth range of the door but need not open the door manually. He just needs to enter the right password through his android application in order to unlock the door. This is a useful concept in places where the security needs to open gates quite usually or need to operate a door from a vehicle without needing to get down from it.

      The command sending functionality is achieved through an android application.   The application provides an interactive user friendly GUI for this purpose. The android application can be operated from any device running on android OS and uses Bluetooth as a medium for sending commands.

As soon as commands are sent through the android device a Bluetooth receiver is used to receive those commands. These commands are then sent to the 8051 micro-controller. The micro-controller processes these commands and then tallies the password to check its correctness. If the right password is encountered it sends command to open the door.
