Weather Monitoring Station

Introduction

Weather variables such as wind speed and direction, air temperature, humidity and rainfall may all be important factors in determining the course of a wide range of events. For example, agriculture has always been heavily dependent on the weather and weather forecasts, both for its control on the quality and quantity of a harvest and its effect on the farmer’s ability to work the land or to graze his stock. Water resources generally depend critically not just upon rainfall, but also other weather phenomenon that together drive plant growth, photosynthesis and evaporation. Just as pollen and seed dispersal in the atmosphere are driven almost entirely by the weather, so too is the direction and distance of travel of atmospheric pollution. Weather monitoring is also important not just in defining present climate, but also for detecting changes in climate and providing the data to input into models which enable us to predict future changes in our environment. The demand for weather data, usually on an hourly or more frequent timescale, has increasingly been met by the development and widespread deployment of automatic weather stations. The NS-WMS-01, provides sophisticated monitoring and logging of essential weather conditions such as temperature, barometric pressure, wind direction, wind speed, rainfall, relative humidity and solar radiation etc. High accuracy sensors are used to serve the purpose. The microcontroller based weather station comes with inbuilt memory for logging of data for several months. Data can be retrieved easily through the USB port. It has GPRS enabled web telemetry for continuous and online transmission of weather data to any server. The instrument comes along with a rechargeable battery and solar panel for uninterrupted power supply. Application areas include agriculture, hydrology, ecology and meteorology. For customized applications, our instrument can come with the best blend of sensors, data logger and accessories accordingly.
