The AcuRite weather station is a great option for people who want to learn more about the weather trends in their area. The three-in-one wireless sensor captures temperature humidity and wind speed and keeps a record with Trends displayed over the last 12 hours. The sensor is completely wireless, and operates and temperatures as low as negative 40 degrees Fahrenheit. The sensor also has a 2-year battery life.
The included weather station is a full color tablet that allows you to see a personal forecast from 12 to 24 hours as well as a 12-hour history of barometric pressure, humidity, temperature, and wind speed.
With the wind speed display, you can see the current wind speed as well as below average in Peak. You can customize the time frames for computing these measurements when you set the unit up.
The history chart will display any changes over a 12-hour time frame. It will automatically cycle between barometric pressure, temperature and humidity. This lets you see how the various weather conditions are trending so you can make an easier decision of how to plan your day.
The display plugs into the wall but also can take six AA batteries to allow for backup in case of a power failure. The sensor must be within 300 feet of the receiver, but can be mounted on virtually any one to two-inch Pole.
The sensor uses a calibrated high speed wind anemometer that is connected to Precision bearings for accurate and precise measurements. The temperature and humidity sensors are also integrated into the main sensor body.
AcuRite is one of the most trusted names in weather prediction technology. This sensor combines the latest methodology and modeling the effects of current localized weather observations to provide a forecast personalized best for your precise location. Additionally, the weather sensor uses a learning algorithm to determine your precise altitude. This Precision in altitude determination helps make your personal forecast even more accurate.
What exactly is Barometric Pressure and Why Does it Matter?
Barometric pressure, simply put, is the measure of air pressure in the atmosphere. Air pressure is essentially the weight of all of the air molecules above you at any given point on the planet. Because of wind patterns, barometric pressure changes all the time and is different depending on where you are. Depending on the accuracy of your readings, barometric pressure can change from one spot to another spot a foot away.
On average, barometric pressure is 14.7 pounds per square inch at sea level. Keep in mind that this is just an average of pressure across the world. Now, as you go higher and live at higher altitudes, atmospheric pressure is going to be much lower. For example, if you live at 18,000 feet above sea level, there are 50% fewer air molecules above you. Of course, there are no cities that high. But Denver, which averages from 5130 to 5690 ft. above sea level, pressure is typically at 12.37 pounds per square inch.
So why is barometric pressure important? It’s because barometric pressure changes with the weather or to be more precise, weather changes as barometric pressure changes. As air moves around the surface of the Earth, it will rise and fall naturally. As it falls it’s going to add to local air pressure and create a higher barometric pressure reading. When air is rising, that causes a region of low pressure. Now remember that hot air tends to rise, and cold air tends to sink.
This lets you know that when hot air moves into an area, barometric pressure tends to fall. Likewise, as a cold front moves in, barometric pressure increases. When the air falls, it begins to warm and expand which stops clouds from forming. When warm air rises it has the opposite effect. Cooling the air causes clouds to form which can create rain or even storms.
This means that being able to accurately track barometric pressure as it changes across an area, is a key facet in accurately predicting weather.
One other reason why tracking barometric pressure is important is because changes in barometric pressure also have an effect on the human body. Some people are much more sensitive to those effects than other people are. For example, low barometric pressure can cause people to have headaches caused by the pressure difference between the atmosphere and your sinuses.
Migraine sufferers can be especially affected. There was a study by the internal medicine Journal where are migraine patients kept a headache diary for an entire year. Doctors were able to find a direct correlation between low barometric pressure and migraine headache onset.
Another physical condition that is often exacerbated by barometric pressure changes is arthritis pain. Nobody is sure why barometric pressure causes joint pain. It may have something to do with how barometric pressure affects the lubricating fluid and the joints or that it affects the nerve pain sensors. However, if you’ve ever heard your grandmother or uncle say that they know a storm is approaching because are joints hurt, now you know why.
The AcuRite Pro color weather station is a great choice for people who want to keep track of their local weather. If you’re looking to get a more accurate forecast for your home, investing in this sensor and control station is a great idea.
