METHODOLOGY

RASHPBERRY PI BASED HOME AUTOMATION:AIM:

To control multiple electrical loads or the home appliances

remotely over internet falling under the basic principles of

Internet of Things-IOT.

Real case scenario application.

The data sent from the webpage upon clicking the buttons, commands are sent through allotted IP fed to it, to any nearby wireless modem which is then received by a Raspberry pi by using PHP commands.

DESCRIPTION OFPROCESS

Relays are then driven as per the command received at the

Raspberry Pi end to handle electrical loads.

The real time data is also seen on the webpage itself that displays the

status of the loads too.

This consists of power supply, bridge rectifier, transformer, relaydriver, voltage regulator, webpage, php commands.

Relay driver provide the necessary current energize the relay coil….

When logic 1 is written on port pin thus turning on relay

OTHER APPLICATIONS

AS WIRELESS EXTENDER. IN ARCADE BOX IN SURVELLIANCE PROJECTS

FUTURE ROADMAP

In upcoming years Raspberry Pi becomes retro computer of the future.

Students can use upgraded system board that is Raspberry pi 2 model which is next generation board & more advance in terms of config.
