![]() The type used on weather stations and hand-held versions uses three cups on a spindle – the wind force on the open side of the cup is greater than that on the rounded side, making the cups rotate. But how do we measure its speed?Ī device for measuring wind speed is known as an anemometer, and there are many different types. As well as meteorologists, many other people are interested in how fast the wind is blowing, ranging from athletes such as parachutists and sailors to those concerned with hazardous winds, such as air traffic controllers and crane operators. Here we use InfraRed sensors to count the rotation of cups in the anemometer.Wind is simply the movement of air, but sometimes this movement can be pretty fast! Those of us in the South of England have recent memories of the St Jude’s Day storm on 28 October 2013 and the disruption caused by gusts of up to 99mph. Using the distance we can calculate the velocity. In cup anemometer we generally calculate the number of rotations takes places for a particular period of time and then using that we can calculated the distance covered. Ultrasonic anemometer is little bit difficult to build by our own and the easiest method is 3-cup anemometer. There are different types of anemometer design like cup anemometer, ultrasonic anemometer, etc. Manual works:Īnemometer is used to measure the wind flow velocity. ![]() ![]() The big and manual work to be done by all hardware hackers is to build their own Anemometer (Wind speed measurement), Wind vane ( Wind direction measurement), Stevenson screen (protection of sensors and to get precise weather data). But we have many sensors like DHT11, DHT22, BMP180, BMP085 to sense weather data like temperature, relative humidity and atmospheric pressure. Commonly a low cost weather station are built to sense weather data's like Temperature, Relative Humidity, Atmospheric pressure, Sea level pressure, Wind speed and Wind direction. I would like to share those detailed steps. But there are only very few in detailed about building those instruments to sense data like wind speed and wind flow direction. There are so many tutorials in Internet to workout with weather station using Arduino, Raspberry pi and so on. To avoid these types of errors, we as hardware activist can build our own low cost weather station and can send these data's to a common web service. But this is not fully true, because the weather station location and your location may be far away and can change the data.įor example : If you are nearer to a sea shore and if the weather station is far away from sea shore then there will be big changes in Wind flow comparing in both region. There are many apps in android to check the weather data in our present location. ![]() Mostly in our area, weather station are built far way by government and private organization and if people like us can grab those weather data from Internet. Weather data's are very useful for evaluation and comparison of climatic changes and effects of global warming. Weather station is simply a thing or instruments which used to measure (sense) weather data from the surrounding environment. As we heard many times about weather station and some people would like to build their own weather station in their home. I would like to share some knowledge about weather station.
