Story

About the project:

Automation industry has witnessed tremendous growth in the last 10 years and achieving portable gadgets for providing automation of devices are the need of the hour. This is because in many cases users will not like to invest money for changing the house wiring for achieving automation rather they would like to invest on a portable gadget that they can take anywhere in the home and the same gadget can provide automation of the device that is plugged into the socket. This is what has motivated us to take up this project and the job has become quite simple with the help of TI technology solutions for IOT applications.

Components used:

MSP432(P401R) from TI

CC3100 BOOSTER WIFI PACK

3 RELAY MODULE

CONNECTING WIRES

3-PINSOCKET (3 Pcs)

MDFboard

Working:

We are Controlling sockets using internet

We have developed a mobile application which sends commands to the Ubidots server which further routes the received command to the WiFi booster pack CC3100. WiFi booster pack in turn send the received command to MSP432 launchpad module. MSP432 module decodes the received data and compares it to check whether a valid code is received. The program that we have written turns all the sockets to ON state if '1' is received and turns them to OFF state if '0' is received.

Summary:

This is WiFi enabled Smart Power Strip that provides you 3 smart plugs capability combined in to one.

The main advantage is we can access our extension board from distance.

You can control it anytime and anywhere.
