The importance of notice board in every academic is well known to us, every time the notices changes iteratively which have to be done manually. Also the importance of room light control is increasing day by day for same academic works. In this paper we are proposing the work using ARM 7-LPC 2138 interfaced with graphical display and Zigbee modem to overcome the above drawbacks. A single ARM 7 is used to display the various notices from HR person’s computer through Zigbee modem. The LPC 2138 is also interfaced with PIR sensor which will sense the absence of human activity within the class rooms and will make the lights/ fans OFF automatically.

Keywords: LPC 2138, Zigbee modem, PIR sensor, MAX 232, 20*4 LCD.
