Wael M El -Medany [18] et. al. proposed a GSM Based Remote Sensing and Control System using FPGA. The system is based on designing and implementing an FPGA chip that is interfaced with a GSM modem to work together as a remote security and control system at the same time. The hardware of the chip has A GSM modem can be a dedicated modem device with a serial, USB or Bluetooth connection, or it can be a mobile phone that provides GSM modem capabilities [18]. GHAS MOBILE APPLICATION The GSM Home Automation System Application is developed using the App Inventor for mobile phones and tablets with Android support having the SMS connectivity option. GSM MODULE: GSM is a digital mobile network that is widely used by mobile phone users. A GSM modem is a wireless modem that works with a GSM wireless network. Various standard commands are used to communicate with GSM. The user when send a operational command to the system, the command first received by an intermediate When we send the message from the mobile to the modem, GSM modem sends the below command serially to indicate that new message is received. +CMTI: "SM",3 . In the above command number 3 indicates the location of the new message. Now we need to read this unread message to display it on LCD. The command to read the message from GSM modem is This project aims to design such system only which just needs an SMS to control the device. The owner of the place will send a particular SMS to switch on or off the particular device in an industry which will further used to automate the complete industry via GSM. Modules Used TTL to RS232 Line-Driver Module Microcontroller 8051 Family To perform these tasks, a GSM modem must support an ―extended AT command set‖ for sending/receiving SMS messages, as defined in the ETSI GSM 07.05 and and 3GPP TS 27.005 specifications. GSM modems can be a quick and efficient way to get started with SMS, because a special subscription to an SMS service provider is not required. Microcontroller Based Substation Monitoring and Control System with Gsm Modem Frequency and send these real time values over GSM network using GSM Modem/phone along with temperature at power station. This project is also designed to protect the electrical circuitry by operating an User can send commands in the form of SMS messages to The proposed system comprises of GSM modem, Microcontroller, various sensors, relays, memory and LCD Display. If the user wants to control the system from a remote place, he/ she has to send the SMS command from his registered mobile indicating the operation of the device. The GSM modem embedded with Microcontroller receives the user's command. side. The incoming information to this device is decomposed into a serial bit sequence [6]. Server: A system that is requiring for runs software to manage the hardware controlling device and to send or receive SMS. GSM Modem: This device is for sending and receiving data, SMS text messages, GPRS data over the GSM network. Hardware The GSM module will be interfaced using PIC16F877A. This MCU will process the SMS received from the GSM module and convert it to suitable duty cycle for PWM pulse to control the speed of the DC motor. 4.3. Motor Driver Dual H-bridge Motor Driver L293D IC will be used as a motor driver to control the DC motor speed and direc- tion. 5. short message service (sms) to organize appliances and the microcon
