SMS Based Home Appliance Control System

After we presented our proposal to our adviser, it is now official that we will make a SMS Based Home Appliance Control System. It took us almost two months to figure out how to make this project at a minimal cost. Now, we have estimated the expected cost of the project and it will only cost less than 2,000 pesos for the hardware.

“Home appliance control system is based on GSM network technology for transmission of SMS from sender to receiver. SMS sending and receiving is used for ubiquitous access of appliances and allowing breach control at home. The system proposes two sub-systems. Appliance control subsystem enables the user to control home appliances remotely whereas the security alert subsystem provides the remote security monitoring.

The system is capable enough to instruct user via SMS from a specific cell number to change the condition of the home appliance according to the user’s needs and requirements. The second aspect is that of security alert which is achieved in a way that on the detection of intrusion the system allows automatic generation of SMS thus alerting the user against security risk.

PC: This unit contains the software components such as the HACS System through which the appliances are controlled and home security is monitored.
GSM Modem: It is a hardware component that allows the capability to send and receive SMS to and from the system. The communication with the system takes place via RS232 serial port. Cellphone can be attached at the place of GSM hardware but it limits the hardware functionality such as sending or receiving of SMS.
Mobile Device: Cellular phone containing SIM card has a specific number through which communication takes place. The device communicates with the GSM Modem via radio frequency. Mobile user transmits SMS using GSM technology.”1

    I need Embedded C code for 89c51 Microcontroller to control the Devices via SMS.

    I want to control 8 Devices by sending SMS from the mobile.

    Requirement :

    If i send message

    Ex: Device1 ON Device 2 ON Device3 ON Device4 ON Device5 ON Device6 ON Device7 ON Device8 ON

    For the above message should be sent in a single message and all the device should be turned ON.

    Similarly if a change the value from ON to OFF then devices should be turned OFF.

    I should be able to select any option for the devices and respective operation has to be performed.

    If its not possible for 8 then at least make it for 4.

    And if possible acknowledgement about the status of Device whether its ON or OFF to the dedicated number.
