Indoor measuring range
The temperature range at which the weather station's internal temperature sensor (see "Measurements") can operate normally. Of course, for normal use, it is need to the temperatures in the room do not go beyond the specified range — otherwise the device will give a warning about the impossibility of measurements in the best case, and at worst it will fail altogether. However, it should be noted here that temperature fluctuations inside residential and office buildings are relatively small, and even in the most inexpensive weather stations, the operating range of the corresponding sensors covers these fluctuations with an impressive margin. Therefore, it makes sense to pay close attention to the measurement temperature in the room only when the device is purchased for non-standard applications — for example, for installation in a greenhouse or in a warehouse with low temperatures.
Outdoor measuring range
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.
Dimensions
Dimensions of the main unit of the weather station. This option allows you to estimate the space required to install the device. However, most modern models are very compact, it makes sense to pay close attention to the dimensions only when you have to install the device in a very cramped place.
Weight
The total weight of the device. In models equipped with external sensors, this parameter is usually indicated only for the main unit, because the weight of the external equipment is small and can be neglected.
