How to Measure the Humidity in the Room

The question of determining the air humidity should be concerned not only physicists and meteorologists, but also ordinary people, especially if most of the people of the day spent in the room. After all, too high humidity adversely affects the health. That is why the humidity must be constantly measured and monitored.

Action of this device is to determine the effect on the degree of humidity special matter. For example, the hair hygrometer uses hair feature - length change under the influence of moisture. There is also another kind of hygrometer, which uses an organic film. However, it is worth remembering that these devices are less accurate compared to the psychrometers. But in the winter season hygrometer - is the main instrument by which to obtain accurate data on atmospheric humidity. In addition, there are several types of such devices: condensing, ceramic, weight, electrolyte. BTW, you can buy the cheap humidity meter at Banggood. Besides, you can easily get other electronic accessories (e.g. RJ11 Detector) there with high quality and reasonable prices.

Psychrometer Using this device, you will get the most accurate result (hygrometer deviation - about 5%). Psychrometer consists of two parts - a wet and dry Thermo sensor. Humidity one sensor is achieved by the fact that it is in a wet cotton cloth. With evaporates and thereby cools the thermometer moisture over time. Simultaneously, the other sensor measures the exact temperature in the room. As a result, the data is transmitted in a special microprocessor which determines the exact air humidity.
