the styrax “electronic status board” has been specially developed keeping process measurement requirements of clean rooms in pharmaceutical industries. The process scanner can measure temperature, rh inbuilt integral sensor, differential pressure inbuilt sensor or three analog inputs or two analog inputs and inbuilt differential pressure sensor. It has on demand dew point display. The scanner has status leds for process violation indication. Rh, temperature and differential pressure will display individually and data transfers to any master device on modbus rtu rs-485 communication. It has individual communication diagnosis led's for scada communication and status application communication. The scanner has inbuilt buzzer for audible process violation. It has keypad to program and calibrate the instrument by user. It has stainless steel modular face plate, which is designed as a mounting accessory for monitor suited for brick and modular wall for clean room applications where you need flush mounting mechanism.   features : advanced microcontroller based process measurement. programmable channel ranges and unit selections. 4 digit, 0.8” bright 7- segment led display for displaying temperature, rh and dp. 10- digit 0.56" bright 16-segment led display for displaying activity. 20- digit 0.56" bright 16-segment led display for displaying name of product. 10- digit 0.56" bright 16-segment led display for displaying batch number. user selectable set limits for process value violation. process parameter status indication with 3 bi-color 3mm leds. inbuilt buzzer to audible process value violation. password protection for calibration and programming mode. software calibration for 3 channels using front panel keypad. modbus rtu multi drop rs-485 serial communication for plc, scada, etc. rs485 interface to batch status application. programmable baud rate between 9.6k/19.2k/38.4k. diagnosis indication of communication with scada and batch status application. user programmable offset correction. brick and modular wall mounting. stainless steel enclosure.

Notice boards play a vital role mostly in educational institutions. The events, occasions or any news, which has to be passed to the students, will be written on the notice boards present in every floor in the colleges or schools. The present system is like, a person will be told the news and he has to update this news on all the notice boards present in the college or school. This will be seen mostly during the examination seasons. The time table or the schedule of the exams has to be given to the students. This will be done by writing the details on the notice boards. But this process consumes a lot time to update the news on all the notice boards and there may be chances that the person responsible may commit some mistakes or he may be absent sometimes. So, this may create disturbances and the entire schedule may be disturbed. To avoid all these, Wireless Notice Board have been designed which completely eliminates the manual work. ZIGBEE is a specification for a suite of high level communication protocols using small, low-power digital radios based on the IEEE 802.15.4-2003 standard for Low-Rate Wireless Personal Area Networks (LR-WPANs). ZIGBEE is targeted at radio-frequency (RF) applications that require a low data rate, long battery life, and secure networking. ZIGBEE protocols are intended for use in embedded applications requiring low data rates and low power consumption. ZIGBEEs current focus is to define a general-purpose, inexpensive, self-organizing mesh network that can be used for industrial control, embedded sensing, medical data collection, smoke and intruder warning, building automation, home automation, etc. The resulting network will use very small amounts of power. The project will be designed in such a way that an XBEE transceiver will be interfaced to the PC through a serial line driver IC MAX232, to transmit the data received by the keyboard. At the receiving end, the controller will be interfaced to the LCD and an other XBEE transceiver. The transceiver receives the data coming from the transmitter and the same data will be fed to the microcontroller . The controller sends this data to the display unit and thus the message given by the user at the transmitter end will be displayed on 16X2 LCD display. This project uses regulated 5V, 500mA power supply. 7805 three terminal voltage regulator is used for voltage regulation. Full wave bridge rectifier is used to rectify the ac output of secondary of 230/12V step down transformer.   Micro Controller : AT89S52 Crystal : 11.0592 MHz zigbee Transcievers Led : 5mm Red LED Max232 Lcd : HD44780 Software Requirements Keil Proteus Uc Flash Embedded C Prog Isp
