Wind speeds are dependent on ground roughness, topology and other factors that affect the speed of the wind. To make a more accurate and detailed resource assessment, it is important to know the frequency of the wind velocity for a particular location.
What is wind speed logger?
A wind speed logger is a device that provides an affordable solution for site evaluation. It supports complex and simple monitoring applications. A wind speed data logger records gust, wind speed, direction, and temperature, time and date, battery voltage along with other wind parameters.
How does it work?
The wind flow velocity data logger can measure wind velocity from a few anemometers for a more complex study which might include multiple speed sensors along with other instruments. It collects data from wind sensors, analog inputs, weather sensors, and system parameters.
The three anemometers include pulse count, gust and wind speed. The logging interval time can be adjusted from 10 to 60,000 seconds. A time interval of 60 seconds is ideal for most applications.
The data logger has to be located a few feet away from the wind measuring sensors, and it must be compatible with almost every type of anemometer available. The data logger can be operated from a direct current voltage source from solar power systems, or from alkaline batteries.
A real-time clock will be there in the system for time-stamping each measurement. The clock will be powered by a battery. All the important data collected are stored directly in an SD (Secure Digital) card.
The SD card provides suitable data downloads and can store data of a few months that are accumulated at 30-second intervals. The data gets logged in regularly and when it accumulates a large quantity, it can be retrieved from the data logger with fewer trips all-round the year.
What are the advantages and disadvantages of data logging?
The information from a data logger will be processed and analyzed in real-time. The weather monitoring equipment can be located in remote areas where access to the internet and electricity may be limited and worse, the services may get interrupted. If such a thing happens, the value of the data will be higher than the data logger itself. Here are some of the advantages and disadvantages:
Advantages of data logging-
Data logging is accurate because there is no chance of human errorThere is no need to have a person on standbyCan be easily installed Time intervals can be frequent and regularIt can be carried out 365 days a year and 24 hours a dayIt can be used in remote locations
Disadvantages of data logging-
In rare situations, if the equipment breaks or malfunctions, there could be a loss of dataBecause the equipment is programmed for taking readings at logging intervals, if something happens in between, the data will not get collectedThe sensors must be calibrated carefully, or else they could be wrong readingsSometimes equipment for such small tasks can be expensive
Measuring wind in an effective way is important both for environmental conditions and data requirements and hence a great data logger will get good results, unlike other generic data loggers because of its data processing capabilities.
