Cold and hot, wet and dry – we live in a world where the weather is very unpredictable. Sometimes it is very hot in the morning, but when the clock strikes midday, the sky starts to rain. Global warming can cause this scenario, which is no longer strange for us. We humans don’t really control the climate. We can only have the best weather stations that can inform us about the weather of the day.
A weather station is an instrument used to observe atmospheric pressure, in order to predict the likely climate that will follow in the local environment. Basically, they are used to predict the weather, in addition to providing accurate temperatures in the local reading, but their functions and accuracy vary dramatically and are influenced by many variables, especially the placement, which is essential for the accurate reading of microclimates.
A typical model can measure temperature with a thermometer, atmospheric pressure with a barometer, humidity with a hygrometer, wind speed with an anemometer and, in some cases, come with a rain gauge to measure rainfall.
The barometer is probably the most important feature and is perhaps the only feature on some models. It tracks the rise and fall of local air pressure and provides, based on these changes, an indication of how likely the weather is to improve or worsen.
In terms of personal stations, unlike professional stations used in the industry, there are two types. First, there are meteorologists who measure air pressure to provide their predictions. Pre-existence usually comes with the ability to display the temperature indoors and outdoors, thanks to a wireless sensor. The wireless sensor can be placed almost anywhere, at the end of your garden, for example, and transmits information back to the central location where your weather station is based on the radio frequency. In most cases, the wireless sensor can be placed up to 100 meters from the base unit, as long as there are no obstructions, such as walls, on the road. Specifications vary, so it’s something to check before buying a weather station. In some cases, it is possible to operate a cable sensor from the weather station, allowing the sensor to be located two hundred or three hundred meters from the base.
The pre-designers further down the scale offer a website that provides an air pressure index for up to three days, which is popular when combined with a weather forecast feature. They can also include a system that allows you to alert you according to defined temperatures, which is useful if you are growing plants, fruits and vegetables, or can suffer when the temperature reaches certain extremes. Leading developers offer many features capable of extracting data from various sensors and producing more accurate forecasts, as well as displaying recordings in a usable manner.
The other option is the completely inclusive climate, which in addition to measuring air pressure accompanies the other meters mentioned above to read readings on temperature, humidity, wind speed and precipitation. They are able to record and retain large volumes of information that can be downloaded to a personal computer or viewed on the unit’s screen.
To operate a personal weather station, all you need is a set of standard batteries or conductors connected to the electricity, depending on the make and model.
