ABSTRACT

We aim to build a low-cost, yet reliable, weather monitoring system capable of acquiring

and recording data. The proposed system has four sensors that measure the Temperature,Humidity, Sunlight, and Wind. The analogue outputs of the sensors will be converted to digital

signals and further processed by a microcontroller. An LCD display is also connected to the

microcontroller to display the measurements. For analysis and archiving purposes, the data can

be transferred to a Printer through a Serial port of Microcontroller or data can be logged in

EEPROM.

Real Time Clock (DS 1302)

DS 1302 communicates with a microprocessor via a simple serial interface. The real-time

clock/calendar provides seconds, minutes, hours, day, date, month, and year information. The end of the

month date is automatically adjusted for months with fewer than 31 days, including corrections for leap

year. The clock operates in either the 24-hour or 12-hour format with an AM/PM indicator.

Interfacing the DS1302 with a microprocessor is simplified by using synchronous serial

communication. Only three wires are required to communicate with the clock/RAM: CE, I/O (data line),

and SCLK (serial clock).

Analog to Digital Converter (0808)

In physical world parameters such as temperature, pressure, humidity, and velocity are analog

signals. A physical quantity is converted into electrical signals. We need an analog to digital converter(ADC), which is an electronic circuit that converts continuous signals into discrete form so that the

microcontroller can read the data.

WORK TILL DATE

Till date we have designed the interfacing of ADC and RTC with microcontroller. The

components have been made available by our company and which is been tested using the bread

board. Then we have designed the PCB layout for ADC and SENSORS using express PCB. We

have also done with the proteus simulation of the interfacing like RTC, ADC and LCD. Code

writing for the ADC, RTC and LCD is been started using keil and in near future we will interface

PRINTER or EEPROM to keep the record of data.

CONCLUSION

The circuit for 24 x 7 Weather Monitoring System has been designed by us in proteus

and also the coding for ADC and RTC is been started which we will implement on the hardware.

We have been also working on interfacing of printer or EEPROM. We have learnt the actual

microcontroller working and also got the knowledge of all the sensors and RTC which we have

interfaced.

Still we are gathering all the required data and information for the whole development.
