Logically, watching weather conditions in your area is very basic day to day thing aside from receiving them technologically on television, on your cellphone, or the radio or thru e mail or pager. Being able to know the upcoming weather helps you in a lot of ways from taking care of your garden or livestock to what to wear before venturing out of your home. The most basic weather device is the cup anemometer. It consists of three or four small hollow cups or hemispheres fixed in a particular manner so they catch the wind and are set on a vertical rod. The wind velocity is measured by the number of revolutions of the cups which is transmitted to an electrical device. This basic weather instrument can be easily made by almost anybody as long as you have the materials needed. The rotating cups should be of the same size to ensure even rotations resulting to more accurate data. The vertical rod used for the rotating cups should be straight and strong enough to hold the weight of the rotating cups so it would be sturdier. The most common problem is the contact point between the rotating cup part and the vertical rod. A bicycle bearing could be used instead of plain metal ring. Therefore, it minimizes friction between contact points and ensuring smooth rotations and a much more accurate data.
Since our technology is much more advance today, devices or advance weather instruments are now being made and promoted. Making a miniature weather station in your own home. But advanced as they are so are their technical problems. Home weather stations now can record temperature, humidity, air pressure, wind strength and direction, and rainfall in one small device. A total whopper for gadget gizmos. But wires can be a hassle crisscrossing across your ceilings and walls down to your electrical equipment not to mention the hassle of letting the wires across to where you want the equipment placed. Sometimes it limits you to only how long the wires the equipment gives. So choosing a wireless home weather station would take all that hassle away. A next technical problem is the radio range. It affects your data and sometimes it has government restrictions thus making your data slow and unreliable. Other times finding the right place and position of the sensor is time consuming and very stressful because you have to consider trees and other buildings even the room that you put the receiver in should be considered. Could be the wall be too thick or is there one wall too many. Having a radio frequency range of at least 300 ft or 91m or more would solve this problem. Another sun being directly in contact with your temperature sensors affecting temperature readings. of course shielding the sensors from direct sunlight would change all that. The most basic problem is the installation of the weather device. You might end up hiring a technician to do the job not wanting to destroy the equipment instead which obviously will cost you unnecessarily. So choose one that is easy to install.
