A weather station is a highly specialized product which can help us in performing a plethora of activities ranging from gauging the weather to conducting research analysis.
This device collates information pertaining to atmospheric condition surrounding its stationed spot.
Thus, the weather station which has been placed at your home can provide you with real-time data pertaining to your neighborhood weather metrics.
Most of us think of a weather station as a highly technical gadget using sci-fi sensors for climate prediction.
However, in reality a weather station brings together multiple weather measuring tools for estimating the climate condition with precision.
Today we are going to take a look at the basic tools used by a weather station for recording and displaying data with optimum accuracy.
This temperature measuring apparatus can record data pertaining to average, low/high as well as indoor/outdoor mercury levels.
The readings received by its temperature sensors get readily converted into meaningful information which can be comprehended by weather stations.
In most cases the thermometers can operate over a range of 100 feet and can even be combined with a small solar panel to dodge battery usage.
The temperature sensor of a thermometer can be further subdivided into three parts:
Thermistors are active resistors which can quickly respond to temperature fluctuations. It is crafted using metallic oxides stored inside glass or an epoxy solution.
Thermocouples comprise of two metals which come together to deliver a measurable voltage which changes every time the temperature moves upwards or downwards.
The electromagnetic system used by thermocouples depends on the position of joining of both these two metals which assists with its correct functioning.
PTD is made up of platinum or similar metals. The level of resistance inside the metal alters in accordance with the changing temperature.
Just a slight alteration in electrical response is enough to signify one-degree adjustment in local temperature level.
This device assists in measuring the atmospheric pressure and thus serves as an extremely crucial part of the weather station.
You can easily analyse the alterations in atmospheric pressure by taking a look at its historical data over a particular surface area.
A barometer sensor typically uses pressure and force for measuring the atmosphere.
The level of resistance is electrically detected by a semiconductor or metal for indicating the pressure level.
The final indicator reveals a voltage level which gets converted into digital form.
A weather station uses the hygrometer for gauging the level of humidity present in the air.
It can provide important information like both relative and absolute humidity as well as percentage of humidity.
The hygrometer is usually placed in close proximity to the thermometer as humidity levels is influenced to a great extent by the temperature.
This capacitor features a sensor using metallic electrode and polymer layer.
Tiny rain molecules are absorbed by the hygrometer to cause a reaction in accordance with changing humidity levels.
This device assists in measuring the direction and speed of winds at a particular point of time. The design of an anemometer can be further sub-divided into three categories:
It sends wind related information by utilizing ultrasonic waves.
The device is intelligently positioned with its erect points directed towards the sky and ample spacing between them.
The ultrasonic waves change speed in accordance with the blowing of wind between the two points.
Data collected from all the points are used to determine the final figures.
This comprises of a weather vane as well as a propeller. The wind is picked up by the wind vane which moves the propeller in similar direction.
Anemometer (cup shape)
It comprises of three cups which can effectively measure the speed and direction of wind. The extra vane helps in confirming the wind direction for extra precision.
This simple device can help in measuring the level of rainfall experienced by a particular area. Rain gauge can also be of different types depending upon its working mechanism with the tipping bucket being the most popular one.
With the growing unpredictability of climate conditions, a weather station can serve as your ultimate nirvana in preparing yourself accordingly to make the most of your daily work appointments.
