IOT base Smart Home Appliances by using Cloud Intelligent Tetris Switch

Industrial device control over IOT based WiFi Module


This paper presents a design and prototype implementation of new home automation system that uses Wi-Fi technology as a network infrastructure connecting its parts. The proposed system is better from the scalability and flexibility point of view than the commercially available home automation systems.

In Industry we have different types of loads at different locations.  We can control all loads at a time from one place (control room) without connecting any physical wire between loads and control room, In this project we are using WI-FI module, AT89S52,TRAIC. In this project , wifi is being used by phone and the loads are operated with it.

In this project we should not connect AC loads directly to microcontroller since   AC may entire  into controller  due to this our controller may be destroyed. To  avoid  such type  of  drawback  we need some drivers. In this project we are using TRAIC   as  load controller (as a  switch)   so we need TRAIC drivers. We have so many   Traic drivers one of them is MOC 3021 used  as a  Traic  driver   in between  Microcontroller  and AC loads

This project uses regulated 5v, 500mA power supply. 7805 and 7812 three terminal voltage regulators are used for voltage regulation. Bridge type full wave rectifier is used to rectify the ac output of secondary of 230/12v step down transformer.
