Ali Turab Bukhari 081220-075AIMSTo capture the data wirelessly by sensorsLogging the data and analyzing it.To gather the current weather readings that can be seen from indoors at any time.record wind speed over time to determine true wind powerMonitoring and calculations of remote temperature and relative humidity Rain measurementsCalculation of wind direction

Objective

Control and monitoring of environmental parameters inside a polyhouse farm, so as to ensure continuous maintenance of favorable crop atmosphere.What is weather station? A facility or location where meteorological data are gathered, recorded, and released. What is data logging? To log and store values. It is commonly used in scientific experiments and in monitoring systems where there is the need to collect information faster than a human can possibly collect the information and in cases where accuracy is essential.

WIND VANE , ANEMOMETER & RAIN GUAGE Anemometer:The cup-type anemometer measures wind speed by closing a contactas a magnet moves past a switch. A wind speed of 2.4 km/h causes the switch to close once per second.

Rain Guage:The rain gauge is a self-emptying tipping bucket type. Each 0.2794 mm of rain causes one momentary contact closure that canbe recorded with a digital counter or microcontroller interrupt input.Wind VaneIt has eight switches, each connected to a different resistor. The vanes magnet may close two switches at once, allowing up to 16 different positions to be indicated. An external resistor can be used to form a voltage divider, producing a voltage output that can be measured with an analog to digital converterFlow ChartSTARTInitialize ADC,UART,LCD Is Data Available ADCConvert to Standard UnitsLCDUART PC GUIYesNo

Advantages Many farmers rely on weather stations to provide them with accurate weather information. From family owned farms and vineyards to the agricultural industry at large, being able to take accurate and reliable environmental measurements is a must as their livelihood depends on having precise and up-to-date weather information around the clock.Many other industries and businesses such as construction companies, utilities and more depend on knowing current and future weather conditions and find weather stations to be indispensable in their line of work.DeliverablesFp1: Learning the basic concepts of atmel controller 1) ATmega16 :Interfacing controller with lcdAnalog to digital conversionUART2) Behaviour and working of sensors3) GUI design FP2:Hardware and programming SimulationProteusLabviewCodeThank You
