A home, office or an organization can decide to set up its free facility that will be monitoring, recording And providing information for weather forecasts, climate change. This facility is referred to as a weather station.The manual observation is taken at least once a day while the automatic measurements and figures are taken hourly! There is essential equipment with sensors that help in collecting data for the station, and they include a thermometer, barometer, hygrometer, and anemometer. We will discuss these five pieces of equipment briefly below


This is a unique device that measures atmospheric temperature. It’s made of two principal components namely the temperature sensor; which is a bulb with a special fluid called the mercury.The mercury indicates any physical change that occurs in the environment regarding the temperature. The second element is the visible scale which is marked on the mercury glass thermometer. These are numerical values that indicate any change that will occur in the atmosphere.

  1. Barometer

This is a scientific device that is used in meteorology to measure the pressure in the air. Its used in forecasting weather and climate change and determining the altitude of an area. What it does is measure the weight of the air in the environment. The pressure tendency is used to forecast short-term weather changes. A barometer is kept at a stationary point in a station and is used to detect and slight pressure change caused by the climate.


This is a unique device used in measuring the moisture content available in the atmosphere.this refers to the moisture in the air.This device works with the concept of both wet and dry bulbs, and these are mercury thermometers where if there is any evaporation of water on the wet bulb the temperature reading will drop hence a low temperature will be shown. The humidity will be calculated by the comparing the calculations of the temperatures given by the dry bulb to the difference in temperature between the two thermometers.

  1. Anemometer.

This is a standard instrument in a weather station and is used to measure the speed and direction of the wind.The information collected will then be analyzed by a meteorologist to calculate the wind pressure. This is usually the force exerted on a winds structure. The knowledge on the wind speed helps indicate a change in weather patterns and can correctly predict some weather conditions like an approaching storm.

  1. Rain gauge

A rain gauge, also known as an udometer is an instrument that is used by meteorologists yo gather collect and measure the amount of rainwater collected. The liquid precipitation which is the product of the condensation of the atmospheric water vapor that comes down due to gravity is then measured over an allocated period.

All these devices play key roles in the determination and predicting of the climate and weather patterns of a given area. Once they are installed and read correctly, an individual or organization can deduce the right weather forecast and plan accordingly their plans based on the weather station findings.
