Home Automation using Android for Aged and Handicap Persons Test phase, srs, design phase and source code final deliverable
Project Domain:
Digital Logical Design
Introduction:
This project allows to manipulate the electrical loads with the assist of android utility. The electrical loads are controlled based totally on Bluetooth enter sign.
This input sign is acquired from the android device. Many times, it becomes too tiring to perform the electrical switches manually every so often. This is a big hassle specially in case of aged or handicapped human beings.
This gadget solves the problem by way of interfacing a unit with domestic home equipment that switches these hundreds based on the enter received from android device.
Functional Requirements:
• The android device can be any android based cellphone or tab having an android OS. The app additionally offers an effective GUI for imparting this functionality.
• An 8051 microcontroller is used on this device.
• The Bluetooth receiver is interfaced with microcontroller so that it will be given the commands and then react for that reason.
• It operates the hundreds via a fixed of relays using a relay driver IC. Relays are used between loads and the manipulate unit.
• This system proves to be very useful for controlling numerous home packages and in industrial setups. The energy deliver setup of the system incorporates a step-down transformer of 230/12V, used to step down the voltage to 12VAC. To convert it to DC, a bridge rectifier is used.
• In order to dispose of the ripples, a capacitive filter is used and it uses 7805 voltage regulator to regulate it to +5V that will be needed for microcontroller and the alternative additives operation.
