Monitoring and regulating humidity levels in the home is crucial to maintaining an optimal indoor environment. A valuable tool for assessing humidity levels is a hygrometer, also known as a relative humidity sensor or indicator. This device measures the percentage of relative humidity (RH) in the air. Here are some key points to note about the hygrometer and relative humidity:

1. 100% RH.

When air at a specific temperature contains all the water vapor possible, its RH is 100%. If RH exceeds 100%, water vapor begins to condense.

2. Variation in RH.

The relative humidity of an air sample can vary with changes in temperature, even if the absolute amount of water vapor in the air remains constant.

3. Types of hygrometers.

There are two types of hygrometer suitable for domestic use (mechanical and electronic). The choice depends on your preferences, but both types work well if calibrated and used correctly.

4. Calibration.

For accurate measurements, it's crucial to calibrate your hygrometer. Consult your user manual for specific instructions on the calibration procedure.

5. Ideal humidity values.

Recommended humidity levels vary according to various factors. Generally speaking, keeping RH between 30% and 50% during the heating season is advisable to avoid condensation on windows. 

In winter, solve humidity problems by eliminating sources of excessive humidity, improving the house's airtightness and, if necessary, using humidifiers. However, keep a close eye on the use of humidifiers to prevent excess humidity and mould formation.
