Temperature and relative humidity have a direct impact on the sense of
well-being and comfort of the residents.
Dry air leads to dry skin, itchy eyes, and irritated nasal passages. It
can cause a bloody nose or an itchy throat and can aggravate symptoms of the
common cold and some respiratory ailments. It also increases static electricity,
which you feel in your clothes and hair and on furniture and carpeting.
Too high relative humidity degrees will result in condensation forming
on windows, walls and ceilings that are colder than the air temperature and
potentially damaging building materials and causing odours in poorly ventilated
spaces. Condensation describes when a gas condenses back into a liquid and is
more often used when referring to water vapour condensing back into liquid
water. Water condensation usually happens when water vapour cools and appears as
droplets on a surface or appears as clouds or water droplets in the sky. The
condensation process will facilitate the growth of moulds and bacteria that can
cause respiratory problems and/or allergic reactions. It provides the conditions
for dust mite populations to grow, which can affect asthma sufferers.
Relative humidity The ratio of water vapour in the
air to the maximum amount of water vapour the air can hold at a particular
temperature is expressed as relative humidity (rH). For example, rH of 30% means
that the air contains 30% of the moisture it can possibly hold at that
particular temperature. When air can hold no more moisture at a given
temperature (i.e. the rH is 100%), the air is said to be saturated.
point temperature The dew point
is the temperature to which air must be cooled to become saturated with water
vapour. When further cooled, the airborne water vapour will condense to form
liquid water (dew). When air cools to its dew point through contact with a
surface that is colder than the air, water will condense on the surface. The
measurement of the dew point is related to humidity. A higher dew point means
there will be more moisture in the air.
Since temperature and relative humidity are basic parameters that
determine the comfort and well-being of residents, most Sentera sensors can
Ventilation in function of temperature and relative humidity level is
interesting in rooms where large fluctuations in temperature or relative
humidity regularly occur, such as kitchen or bathroom.
CO2 sensors with visual and audible alertToo high CO2 concentrations? Sentera CO2 sensors are now available with audible alert. On top of that, the green, yellow and red LED offer a clear, visual indication of the CO2 level. The supply voltage is 230 V or 24 V.>>>
