What is a humidity sensor and how is it useful?


!±8± What is a humidity sensor and how is it useful?

Humidity sensors are in the homes as part of the HVAC (heating, ventilation, air conditioning,) used in office buildings and industry. You are in places that are held high humidity and low, with a constant humidity must be maintained affected. A moisture sensor, which is also called a hygrometer, a device that measures the moisture in the air. The humidity sensor monitors the electrical changes in relation to the amount of moisture in the air. And 'to useControl of such machines, such as air conditioners, humidifiers, dehumidifiers, and adapting to changes in the level of moisture in the air.

Hygrometers are useful for people who suffer from health conditions that are exacerbated by high humidity. How can a person with allergies or asthma with a humidity sensor, low humidity because it may worsen these conditions and too much moisture, the growth of fungi, bacteria, mold and mildew that can cause these conditions worse.They are also for people with wineries who want to maintain a constant temperature and humidity, so do not ruin good wine. As well, hygrometer for storage of valuables such as antiques, will be damaged if exposed to moisture can be useful. The sensor of the humidity sensor detects changes in electrostatic air to varying moisture in the air around them.

The advantage of these sensors in the industry, are allowing for accurate measurement and recording ofMoisture data. The data logger can be used to monitor in real time and sends a warning if it suddenly changes. Once the sensor detects changes in the measurement is then converted to air and moisture values ​​in a data logger. The voltage variations in digital measured values ​​show the amount of moisture in the air changed. You can choose between a few number of data loggers in an application or a data logger for monitoring wider distributed locations. It makes sensemapping and validation, and data acquisition and recording, for reports.

Three types of sensor technologies are resistive, capacitive sensing and thermal conductivity. Resistive sensors are useful when used in remote locations. Capacitive sensors of humidity are beneficial for large surfaces and tolerance condensation. Thermal conductivity sensors are advantageous in corrosive environments that have high temperatures. The type of sensor used depends on the type of environment. Trade andOffice buildings often have moisture sensors in their HVAC systems, which helps you breathe clean air safe and healthy. Humidity sensors for industrial applications for the production of moisture-sensitive materials. As well, moisture sensors to collect data from weather stations and marine research in which the humidity should be measured and evaluated for some time to model and forecast will be used recorded.

Advances in technology have mademoisture as possible for a number of reasons, such as to maintain a healthy indoor air, to protect items from moisture stress and control for research applications. There are a number of online companies that specialize in providing quality hygrometer, which is extremely accurate and resistant to damage by physical and chemical agents.
