IoT based Washing Machine Control Algorithm

Are you looking for IoT based Washing Machine Control Algorithm to send and receive a command from the server? Here is the algorithm that helps you to write your own logic.

Declaration: Washing Machine connected with Raspberry Pi for all the IoT based command. You can also implement some other device like Arduino. This tutorial does not include the IoT based Command.

PushCommand: Send data to the Server through Raspberry Pi 

PullCommand: Receive data from the Server through Raspberry Pi 

Step1: IoT based command to washing machine to start
Step2: If Machine Started
Step2.1		If (Drum Loaded with Cloth ) Then
                PushCommand  ← Update drum weight and height
                (Server Process the data:
             If (Drum Weight > capacity)
       Generate Notification and return fail error
                   Display Error Message  ←  PullCommand )
                Ack   ←  PullCommand
                If ( Ack == Success ) Then
        Fill drum with water according to drum weight and height
                    PushCommand ← Notify about the water level
Step 2.2	    Ack ←  PullCommand
                    If Ack == Success Then
                       If (is Detergent available) Then
                     PushCommand  ← Notify With Success
                           Ack ←  PullCommand
                           //Washing Cycle
                           If Ack == Success Then
                         Door.Lock= true
                               PushCommand  ← Notify
