InfraRed Remote Switch

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 up to 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 switches on/off the appropriate Device. The Range of the system is up to 10 meters. The project can switch on/off electrical devices of maximum load current of 5 Amperes. High power loads can also be connected by changing the Relay. The conditions of the devices are stored in the EEPROM IC.

This remote-controlled switchboard project utilizes an AT89C52 microcontroller as the core processing unit, which is an 8-bit microcontroller from the 8051 family. The microcontroller is responsible for interpreting the infrared (IR) signals received from a standard remote control. The system can manage up to six electrical devices, each being controlled through individual relays. The relays act as switches that can handle a maximum load current of 5 Amperes, enabling the control of standard home appliances.

The infrared receiver module is connected to the microcontroller, allowing it to detect and decode the signals transmitted by the remote control. Each button on the remote corresponds to a specific command that the microcontroller interprets to switch the relays on or off. This feature allows users to control multiple appliances from a distance of up to 10 meters, providing convenience and flexibility in managing home devices.

To ensure reliability and maintain the state of the devices even after power loss, the system incorporates an EEPROM (Electrically Erasable Programmable Read-Only Memory) IC. This component stores the operational conditions of the devices, ensuring that the last state of each appliance is remembered and restored upon reactivation of the system.

For applications requiring higher power loads, the circuit can be modified by replacing the relays with higher-rated ones, thereby accommodating devices that exceed the standard 5 Ampere limit. The design of the circuit involves careful consideration of the power ratings and specifications of all components to ensure safe and efficient operation.

In summary, this remote-controlled switchboard project exemplifies a practical application of microcontroller technology in home automation, offering a user-friendly interface for controlling multiple devices with ease. The integration of EEPROM for state retention and the flexibility of relay configuration further enhance the functionality and adaptability of the system in various household settings.This Project REMOTE CONTROLLED SWITCH BOARD is used to switch on/off the Home Appliances by using a standard Remote control.
