Comparison TFA Spring vs La Crosse WS6828

The number of sensors in the weather station kit determines how many parameters can be simultaneously monitored in different areas. Typically, the basic set includes one external sensor that measures temperature and humidity outside, but more advanced models support up to three or even eight additional modules. However, you shouldn't chase after the maximum configuration, since several sensors increase the model's cost. With future needs in mind, you can consider options with the required number of sensor connections. Then, you can purchase the sensors according to your preferences and needs.

The maximum distance to the main unit of the weather station where an external sensor can be placed. For wired versions (see "Type of external sensor") this indicator corresponds to the length of the standard cable; for wireless, a guaranteed radio communication range is usually indicated within the visibility limit, provided there is no interference or foreign objects in the signal path. Anyway, it should be taken into account that the maximum installation range is usually less than the claimed range in fact. This is due to the fact that the wire can rarely be laid in a straight line, and the radio signal, in turn, is affected by obstacles and electromagnetic interference. Therefore, it is worth choosing a weather station for this parameter with a certain margin.

The temperature range for which the external temperature sensor of the weather station is designed (see "Measurements"). This parameter must correspond to the temperature differences that this sensor may be exposed to during operation — otherwise, malfunctions and even hardware failures are possible. Of course, it is worth choosing a model according to external temperature, taking into account the climate in which it is planned to be used; at the same time, it is worth taking a certain margin both in the lower and in the upper side. The last is connected not only with the possibility of climatic fluctuations, but also with the fact that outdoor equipment can be heated from direct or reflected sunlight; this, of course, must be avoided in every possible way, but it is not always possible to find an perfect fitting location for the sensor.

Ability to display the comfort level on the display of the weather station.

The overall comfort of an individual in specific conditions relies not just on air temperature but also on factors like humidity and outdoor wind strength. Display features for comfort levels vary between indoor and outdoor conditions. Indoors, the device typically assesses the combination of temperature and humidity, offering an overall comfort conclusion ranging from "good/bad" to intermediate options. Outdoors, it introduces the concept of "perceived temperature." This accounts for the impact of strong winds and/or high humidity, where the air feels colder than the actual temperature suggests. For instance, -5 °C with these conditions might feel as unpleasant as -8 °C in dry, windless weather. Perceived temperature data provides a more accurate assessment of external conditions, aiding individuals in making informed decisions, such as choosing appropriate clothing.

Modern weather stations can support either the first or second option separately, or both. Anyway, working with a comfort level implies at least the possibility of measuring humidity (see above).

— Display of the temperature trend. This "weather forecast" relies on recent temperature measurements. A decline in parameters suggests an impending cold spell, while an increase indicates imminent warming. The function predicts whether temperatures will rise or fall in the very near future.

— Backlight display. The display of the weather station incorporates a backlight feature, enabling information readability in low-light to complete darkness. While this consumes energy, it is particularly relevant for self-powered models. However, since the backlight is typically used for only a few seconds, the associated additional costs are minimal. The backlight may come in various colors and, in some instances, serves decorative purposes.

— Clock. The weather station includes its own clock, initially displaying the current time. However, the clock's data can be used for additional functions like recording temperature extremes and operating an alarm clock. Clocks can be electronic or analog, typically aligning with the weather station's mechanism type. Some models even offer the option to synchronize time precisely through radio signals.

— Alarm clock. The weather station features an alarm clock function, emitting a sound signal at a user-set time. Beyond waking up, this signal can serve various purposes, such as event alerts or task reminders. As alarms inherently require a clock (see a...bove), the available signals vary among models — ranging from a standard sound to multiple options. Advanced models may even permit users to download custom sound files (see "Connecting to a PC").

— Calendar. Availability of a calendar function in the weather station. The simplest option involves at least displaying the current date and day of the week, advanced features may include viewing a calendar table for a month or even a year. The calendar can be used not only by itself, but also for other functions — primarily informing about sunset/sunrise (see above).

— Moon calendar. The presence in the weather station of a calendar that displays the phases of the moon. This information can be used for a variety of purposes, from monitoring tides to finding the best time for gardening or beauty/medical treatments. The moon calendar is usually combined with the usual one (see above).

— FM receiver. The weather station includes an FM-range receiver, enhancing the user experience with access to a variety of stereo music stations. However, it's important to note that FM broadcasting has a limited range, typically within line of sight (a few kilometers). This function may be less useful in remote areas far from cities. Optimal reception requires an external antenna, which can be a traditional telescopic antenna or the wire of an external sensor or headphones.

— Projector. The weather station features a built-in projector, enabling the display of various data (weather, time, etc.) on walls, ceilings, or other surfaces, essentially transforming them into impromptu displays. This projection method can be more convenient than viewing information on the main device display in certain situations. However, such models tend to be expensive. The projector typically takes the form of a rotary unit, allowing optimal adjustment of the projected "picture" position.

The weather station's design includes specified placement options for the main unit. While this parameter can be somewhat flexible — such as wall-mounted devices used on tables or creative methods for hanging tourist models on walls — only standard options explicitly stated by the manufacturer are considered in this context. Some models may offer multiple claimed placement options.

— Desktop. Placing the weather station on a table or a similar surface, like a shelf or window sill, is a straightforward and effortless installation method. It provides convenience, allowing for easy relocation when needed. However, the limitation lies in the availability of free surfaces, and there's a risk of inconvenience, such as accidentally knocking the device to the floor.

— Wall. Mounting the weather station on the wall using a hook, nail, or similar device is a space-efficient option, offering flexibility in choosing installation height. This method minimizes occupied space, yet the installation process is more complex, often requiring wall drilling.

– Portable (tourist). Portable weather stations, intended for on-the-go use, are not meant for permanent installation, although that option is also feasible. Designed for hikers and travelers, these compact devices are pocket-sized, easily fitting into bags or backpacks. Their design may include features for easy attachment to equipment, su...ch as handles or carabiners, but they typically lack options for table installation or wall hanging. Portable weather stations usually do not use external sensors, and their cases are reinforced for increased protection against dust and moisture.
