The project presents a digital circular board and a smart home automation system for hospitals, railway stations, bus stops, institutions & industries using Android, GSM Module and ARM-7. This idea provides the users with a simple, fast and reliable way to keep up important circulars in Liquid Crystal Display (LCD). The message can be sent through an android application by using proposed system to the GSM SIM900 module. Similarly, a smart automation system has been developed to control appliances like lights, fans, machines and digital boards in hospitals, railway stations, bus stops, institutions & industries These Appliance can be switched ON or OFF using the android application, the appliances can be controlled and notices or circulars can be put up in an LCD display from any location in the world. The project consists of a 32-bit ARM based microcontroller LPC2148 Development Board, GSM SIM900 module, an LCD, The proposed system can be used anywhere irrespective of the place of deployment provided mobile network connectivity is available. A GSM MOBILE based system is flexible, durable without any risk of getting hacked. Such a system has a low cost of installation and maintenance
