With an Assembled & Tested PCB

DIY kit comes with an Assembled and Tested PCB ensuring 100% output guarantee. Includes hardware for assembling project from scratch. Fully supported by elaborate documentation, audio visuals and tools to independently carry out the project work.


The main objective of this project is to develop a device that controls the home appliances through SMS with integrated acknowledgement feature. Unlike the conventional system present in houses, where one has to manually switch on and off the appliances.

The proposed system allows the owner of the house to control the appliances by just sending an SMS to the device and then also receiving the status of the same via return SMS.

This is extremely convenient for users as they can control their house loads any time and from any place in the world. An example of how this technology can make our lives better is that when a person is travelling and wishes that the moment he enters his room, it should be cool enough to make him comfortable.

In such a case, with the help of this system, he can switch on the AC while he is travelling. An SMS is sent to the GSM modem which is interfaced to the microcontroller. The modem receives the message and sends the command to the microcontroller which processes this and initiates a mechanism that activates a relay to control the corresponding home appliance.

An added feature of this system is that the owner can get the status of all the loads (whether on or off) in the house by sending a status query SMS to the base station. All the status can also be seen on an LCD display interfaced to the microcontroller.
