GSM BASED HOME AUTOMATION USING AVR

PROJECT TYPE

Microcontroller(ATMEGA16)hardware design with software development (Device Driver).

 PROJECT DESCRIPTION

                This Project “GSM BASED HOME AUTOMATION USING AVR MICROCONTROLLER” is used to control the devices in home as well as in industries, Banks, and also in Remote areas. Conventionally, wireless-controlled appliances use RF circuits, which have the drawbacks of limited working range, limited frequency range and limited control. Use of a mobile phone for device control can overcome these limitations. It provides the advantages of robust control, working range as large as the coverage area of the service provider, no interference with other controllers and up to twelve controls.

                  In this project, we control home appliances either AC Device or DC Device controlled by a mobile phone that makes a call to the mobile phone attached to the control board. In the course of a call, if any button is pressed, a tone corresponding to the button pressed is heard at the other end of the call. This tone is called ‘dual-tone multiple-frequency’ (DTMF) tone. The controller perceives this DTMF tone with the help of the phone stacked in the control board and operate.

Control your PC & Home Appliances with TV remote using Microcontroller

PROJECT TYPE

Micro controller(AT89C51) hardware design with software development (Device Driver). Atmel micro controller (AT89C51) based.

 PROJECT DESCRIPTION

         

Now you can control your mouse cursor and windows media player with your TV remote... So when you are watching a movie or listening songs on your PC, you need not to get up from your seat to change the volume or to change the track.. you can simply use your TV remote to do this for you from the sensors, and this signals operated under the control of software which is stored in ROM. We also providing a control system using same remote, you can control your needed home appliances or a devices that are operate on AC/DC its a multipurpose remote controlling system.

AUTOMATIC STREET LIGHT CONTROLLER USING AT89c51 MICROCONTROLLER

The aim of this project is to reduce the power consumption as well as maintenance by providing the Photo sensor that switches the light on and off automatically. The main feature of the Photo sensor is it’s a light dependent resistor. A small hardware model, which is as real as real world application, is built in this project. As the light falls off these sensors switch on the street light and vice-versa.

Automatic plant irrigation using Microcontroller

SECTION 1: PROJECT TYPE

Micro controller (AT89C51) hardware design with software development (Device Driver). Atmel micro controller (AT89C51) based.

SECTION 2: PROJECT DESCRIPTION

         

The Project presented here waters your plants regularly when you are out for vocation. The circuit comprises sensor parts built using op-amp IC LM324. Op-amp’s are configured here as a comparator. Two stiff copper wires are inserted in the soil to sense the whether the Soil is wet or dry. The Microcontroller was used to control the whole system it monitors the sensors and when more than two sensors sense the dry condition then the microcontroller will switch on the motor and it will switch off the motor when all the sensors are in wet. The microcontroller does the above job it receives the signals from the sensors, and this signals operated under the control of software which is stored in ROM.

pollution control using ZIGBEE

Temperature and  Air pollution monitoring system using   Zigbee networks for Ubiquitous-city

Abstract:

The innovative Ubiquitous-City was born through convergence of construction, home applications and culture, with development of up to date information technologies and ubiquitous IT.

The U-City can be applied to a variety of special situations for managing functions of each city efficiently. This paper focuses on implementation of air pollution monitoring system.

First, each sensor was tested after survey about market trends of a variety of sensors for detecting air pollution. Second, wireless communication modules for monitoring system were developed using wireless sensor networks technologies based on ZigBee.

And then a performance of modules was estimated in the real-fields. Through software programs written in C for efficient routing in wireless networks. Finally, integrated wireless sensor board which employs CO2, temperature /humidity sensor and a ZigBee module was developed.

This paper accelerates the digital convergence age through continual research and development of technologies related the U-City
