Weather sensor (definition)

Weather sensor — is a device that measures various meteorological parameters such as air temperature, humidity, wind speed and direction, and atmospheric pressure. This data is used to optimize the operation of heating, ventilation, and air conditioning systems (HVAC), as well as for controlling automatic systems in buildings.

Weather sensor: main features and functions:

1. Measured parameters:
   • Air temperature: Determines the current ambient temperature.
   • Humidity: Measures air humidity levels, which can affect comfort and the efficiency of heating systems.
   • Wind speed and direction: Affects heat loss and air circulation.
   • Atmospheric pressure: Can be used to determine changes in weather conditions.
2. Differences from temperature sensor:
   • Functionality: The weather sensor collects a wider range of data compared to the temperature sensor, which only focuses on measuring temperature.
   • Application: The weather sensor is used for complex analysis and control of systems based on several meteorological factors, while the temperature sensor is used to monitor the temperature at a specific point or area.
3. Installation and integration:
   • Installation: The weather sensor is usually installed on the outside wall of a building or at a dedicated weather station where it can reliably measure the surrounding meteorological conditions. The installation must take into account protection from extreme weather conditions and the ability to freely flow air for accurate measurements.
   • Integration with a boiler or weather controller:
     • Connection: The weather sensor can be connected to heating or ventilation control systems via wired or wireless interfaces. It can transmit real-time data to controllers and regulators.
     • Weather regulator: This controller uses data from the weather sensor to automatically adjust the operating parameters of the heating system. For example, based on the outside temperature and humidity, the weather controller can adjust the water temperature in the heating system to maintain comfortable conditions indoors and minimize heat loss.
     • Automation: Integration with automation systems allows for more precise and efficient control of the heating system, improving energy efficiency and comfort.
4. Examples of use:
   • Optimization of heating operation: Adjust the temperature according to outdoor conditions to maintain a comfortable climate and reduce energy costs.
   • Preventing pipes from freezing: Control of freeze prevention systems based on temperature and weather conditions.
   • Energy saving: Adaptation of system operation depending on weather changes to maximize solar heat or minimize heating costs.

Weather sensor plays a key role in the control of modern heating and ventilation systems, providing precise and dynamic regulation based on external meteorological data.
