This paper is used widely for notice boards particularly focusing on Wi-Fi based digital notice boards and GSM Technology .We can find Wi-Fi based digital notice board in schools, colleges,railway stations, airports and work places.These boards utilize Raspberry Pi as a receiver connected to local Wi-Fi networks. To send information to the Raspberry Pi, the sender must first connect to the corresponding Wi-Fi network. Wi-Fi has a maximum range of about 100 meters, information exchange is restricted within this range. GSM technology is utilized for transmitting information to digital notice boards emphasizing its versatility in various projects such as data acquisition systems and controlling multiple devices. This involved using a GSM module at the board to receive text messages from authorized users.Notices can be in various formats such as docx, pdf, images, videos. An authorized user can send notices from their PC or smart devices to the Raspberry Pi connected to the display monitor via Wi-Fi.The review touches upon the widespread use of GSM technology in various projects, emphasizing its role in data acquisition systems, teaching and learning systems, and controlling multiple devices.An application installed on the administrator's mobile phone includes a speech-to-text converter for sending messages.
