hi friends, i want to make a wifi controlled 3 pin multi plug type device which can be switched on and off remotely, so that i dont need to walk a long way to turn it on every morning
Please suggest any other modules which will be cheaper/better over it
also any ideas for power switching circuit will help
You can use HC-05 Wireless Bluetooth RF Transceiver arduino Module

Use an Arduino n ESP8266 , relays
You will be able to control it via a dedicated app or via web browser in your phone it self !
Using an RPI is also an option ! If you can describe what you actually want bit more deeper i can answer deeper
hi arun, arduino with wifi and relay is exactly what i am talking about, thought of using ardudroid
I want to make a 3 pin multipin adapter which can be operated wirelessly so that i can connect all my ac equipments externally with an app/browser
sauank thanks for the info, but i'm looking forward to wifi controls
by three pin multi pin multi pin i think you are talking about three individual controls , ie three sockets ( three different appliance )
next is to fix your platform Arduino / RPi
which one you prefer
i prefer arduino and i can handle ide, never worked with rasberry pi
by 3 pin multipin i meant 3 pin normal socket(just 1)
Put a high capacity relay on the live wire. Ensure clean power supply to the arduino. Bluetooth is not very reliable.. Wifi is a better alternative. But if you willing to have a separate remote, use the nrf24L01 modules. No headache of wifi, simpler control and less susceptibility to electrical noise.
as a3ruz said - esp8266 is the way to go ,

check out the above - this uses nodemcu ... it is easy .
I have personally done this and can confirm this works. just use a transistor and solid
state relay to switch power.
another option is to get one of these

and set it so that your geyser switches on and off at particular times
@Roby as saikat said you can check out his first URL !
but i think you can't operate this as alone ( not sure about this )
you must connect your ESP8266 to an existing wifi network , eg your home network
then your phone must be also connected to the same network , you will be using modules IP to control
actually you can operate the esp8266 alone .... that is it will create its own wifi network
just set it up as an access point instead of a station.
read the nodemcu Lua code snippets .
once it creates its own network it is a simple matter of logging in to the network with
your cellphone and pointing a browser to the ip address.
thanks saikat, last rides , arun
will try it and update
Thanks for that info @saikat
