Abstract:
This Project REMOTE CONTROLLED SWITCH BOARD is used to switch on/off the Home Appliances by using a standard Remote control. The system is used to switch on/off upto six electrical devices. All the above processes are controlled by the 8 bit Microcontroller AT89C52. The Microcontroller receives the Infrared Signal from the receiver and it decodes and switch on/off the appropriate Device. The Range of the system is unto 10 meters. The project can switch on/off electrical devices of maximum load current of 5Amperes. High power l ....etc

Abstract:
This Project is used to control our household electrical devices from any where through the cell phone. The circuit consists of a DTMF tone detector and a powerful 8 bit Microcontroller AT89S52. The microcontroller controls all the system. In this project we control total six devices.

The Microcontroller senses the DTMF signal through the DTMF decoder IC MT8870 and it switch on/off the corresponding devices according to the user need. The circuit has an inbuilt phone ring sensor circuit and the system will take over the ph ....etc

Tele Remote Switch

INTRODUCTION

Controlling devices using switches are common. From a few decades controlling devices using remote control switching like in fared remote control switch wireless remote control switches light activated switches are becoming popular. But these technologies have their own limitation. Laser beams are harmful to mankind.

Some technologies like IR remot ....etc

IR SWITCH AND REMOTE CONTROL


CIRCUIT DIAGRAM :
IR DETECTOR CIRCUIT :


1. The detector circuit uses an IR detector TSOP 1738 commonly available in the market. This is tuned to detect IR pulses at 38Khz frequency and also it tuned not to respond to stray IR coming from natural light or any other source like tube light etc in your home.
2. Since IR detector can produce a sequence of signals when it detects IR radiation we are using a buffer which will, sort ....etc

Definition

Cellular through remote control switch implies control of devices at a remote location via circuit interfaced to the remote telephone line/device by dialing specific DTMF (dual tune multi frequency) digits from a local telephone. This project Cellular through remote control switch has the following features

1. It can control multiple load (on/off/status each load)
2. It provides you feedback when the circuit is in energized state and also sends an acknowledgement indicating action with respect to the switching on of each load ....etc
