Summary of GSM based home devices control system
This article describes a GSM-based home automation system enabling users to control appliances via SMS from anywhere. The system sends an SMS to a GSM receiver, which forwards the command to an 8051 microcontroller. The microcontroller processes the request and activates relays to switch devices on or off, sending a confirmation SMS back to the user. This setup is ideal for domestic and office use, allowing remote monitoring and operation of lights, ACs, and other appliances without manual intervention.
Parts used in the Home Appliance Control System:
- DB9 Connector
- Capacitors
- Diodes
- Transformer/Adapter
- IC
- MAX 232 IC
- Transistors
- PCB and Breadboards
- Push Buttons
- IC Sockets
- SIM 800 GSM Module
- Resistors
- Cables and Connectors
- LED
- Switch
- Lamps
The project aims at a system allowing user to control home based appliances through Sms along with acknowledgements. Here user need not switch home appliances on and off manually.
Our system allows user to operate these devices through sms, also the status weather the device is switched on or not is sent to user via a return sms. This can be used by domestic users and company users to operate as well as check status of home and company appliances from anywhere in the world.
It is a very convenient system for users since it allows them to easily control and monitor these appliances from anywhere. An example is that a person may switch on his House or office AC 15 minutes before he arrives so that he gets a cool environment as soon as he reaches there.
The system works in the following manner, the sms sent by user is received by the Gsm receiver and then sent to an 8051 microcontroller in order to process it. The microcontroller then activates the appropriate relay for that appliance and controls it.
