1 Introduction

In earlier days people used the paper as the medium to convey anymessage. The paper material, which is made of pulp of the tree,will be scarce after few years. It is mandatory to save the trees byemploying digital technology rather than the conventional method.Printing a paper requires the quantitative manpower. This conven-tional method is very costly. An alternative to this conventionalmethod is efficient to use the digital media and digital technology.Notice boards play a vital role in conveying the messages to manypeople at the same time. Notice boards are used in Institutions,Organizations and many public places. In earlier days printed pa-per is used to display on a notice board. These conventional noticeboards are not so interactive for the modifications in the messagewhich is to be conveyed. Also requires huge amount of resourcesand manpower. A digital notice board can be replaced in place ofconventional notice board to make more interactive and adaptable.Here in which reduces the manpower and resources.The smart notice board uses the digital technology and the elec-tronic components/modules. It is implemented to display the noticeor message which is more convenient for the administrator in termsof displaying, modifying and viewing of the notices/messages.In the paper [1], a smart electronic notice board is implementedusing Wi-Fi, in which a wireless transmitter sends a notice usingWi-Fi Protocol. The disadvantage of this system is the informationcan be passed about 100 meters distance range only. A remote userwith more than the specified distance cannot access to this system.In the paper [2], an Android controlled E-notice board was devel-oped which uses the GSM technology. The disadvantage of thissystem is, it was developed by using GSM technology and it wontuse the IoT. As a result the system is not more user friendly. In thissystem the notice which will be displayed is limited to the messagelength of 160 characters only. Also the system is more costly.A survey paper on Android controlled notice board [3] was pub-lished by Saloni sahare, Rajat kadwe, which compares the SMS,controlled smart E-notice board and Bluetooth based LED display.In this paper the both the systems which are implemented have thelimitation of the message length which is to be displayed.A wireless electronic notice board using GSM technology [4] has

been implemented by N. Jagan mohan reddy, G.Venkareshwarlu.In this paper, GSM technology is used to send and control the no-tice board by an authenticated user. In such implementation thedisplay message is limited to few characters only. As a result itcannot be possible to display long text notices. So the design is notuser friendly.A wireless digital notice board using GSM technology [5] has beendesigned by Ramchandra K. Gurav, Rohit Jagtap. In this paper,the implemented system can display the notice from an authorizedperson and sends it to GSM module of digital notice board. In thisdesign also the message length is limited. Again the system is notuser friendly.In the paper [6], display message on notice board using GSM tech-nology has been implemented. In this design, when the user sendsa Short Message Service, it will be received by the GSM modem ofthe receiver. This message will be displayed on the LCD moduleof digital notice board with the help of microcontroller. In thisdesign, the notice text length is limited to a standard SMS lengthonly. Also the system does not work in case of network failure.In the paper [7], SMS based wireless notice board with monitor-ing system has been implemented. The system is designed usingARM-LPC2148 interfaced with Graphical Display. In this imple-mentation multiple displays along with a decoder are used to selecta particular display. The information is sent to the correspondingdisplay monitor through an ARM controller by using GSM tech-nology. In this design, all the notices are documented and a recordmay be maintained for future purpose. In this design, the moni-toring system consists of an image sensor to capture the images forthe specified duration and those images can be stored in a PC. Thissystem has the limitation of less display size.A wireless electronic notice board using Zigbee [8] has been imple-mented by Ajinkya Gaikwad and Tej Kapadia. In this design, thesystem uses the Zigbee protocol for wireless transmission of notices.Also, the distance between the user and the display module is lim-ited to 100 meters only.The Internet of Things (IoT) is used to sense, control and commu-nicate among the all interconnected devices like sensors, actuators,display devices and the microcontroller. In this IoT technology,each thing is uniquely identifiable by an embedded operating sys-

tem using internet infrastructure. According to experts estimationthe Internet of Things (IoT) [9] will consist of about 30 billion ob-jects by 2020. The IoT technology has been widely used due to theintegration of various technologies like wireless, machine learningand sensors and embedded computing system. Several applicationsof IoT include in smart home, enterprise, industrial management,agriculture and environmental monitoring.In this paper it has been proposed a smart notice board which canbe controlled by an authorized person or administrator in spite ofany distance between that person and the system. To make thesystem more user friendly an android application is developed tomonitor and control the smart notice board. The time consump-tion, resources and manpower of conventional notice board werereduced by implementing this system. The proposed system is astep forward to achieve the Green IT and Automation. It is alsoa cost effective solution over the earlier conventional notice boardsystem.
