In the olden days when there were no rain gauges or barometers, people used a very innovative instrument to predict the weather. This instrument was nothing but a flower that grows on a plant named scarlet pimpernel. If the purple, white or scarlet flowers are closed up, then you can expect rains or clouds. On the other hand, if you see the flowers in full bloom then you can be rest assured that the weather will be clear. This is why these plants were known as 'poor man's weatherglass'. Most of the times, they were more accurate than the weathermen of those days.
However, in today's age you don't need to search for these flowers in the woods. There are more convenient and accurate options that can tell you about the weather from the comfort of your home. One of these options is the electronic weather station
These are wireless gadgets that are easy to handle and carry. They can tell you about things like the rate of the rainfall, the direction of the wind and the speed along with humidity, air pressure and temperature. Most of these gadgets can also predict storms as well. The underlying principle is quite simple. The classic sign of a sudden storm is a steep drop in the air pressure. Therefore, if your electronic weather station records a low pressure in the air, it will warn you in advance. This is quite useful for areas that are known for problems like storms and cyclones.
These days, the electronic weather station is no longer the ugly and bulky instrument of the olden days. They have a modern exterior that looks sleek in appearance. People who like the more traditional look in their instruments can change the appearance without affecting the functionality and design.
An electronic weather station can be used at home, school or in the office. Some of the more tech savvy models come with all kinds of software and the required apparatus to connect to the PC. The wireless technology is pretty neat. The remote sensors are stationed at different parts of the house. These sensors record the fluctuations in the environment and transmit the data to the main unit located inside the house via radio waves. The electronic weather station will not just record the temperatures outside but also inside. Most of these units can also update the clock and the calendar automatically.
In an age where technology is so prevalent, and other changes are affecting our weather, it's difficult to determine or predict the weather. Winters, summers and even monsoon have become more erratic than ever. Many times, people on television and radio often miss out on the vital points and predict the weather based on past data or their experience.
Avoiding inaccurate forecasts or just to verify, it's a better idea to have an electronic weather station of your own which can accurately predict the local weather. Moreover, it's a gadget that can even help you to impress your family and colleagues. After all, who would not want to know the weather and its many variations before hand?
