Humidity monitoring

Relative humidity (RH) is a measurement of the amount of water vapour present in the air and is stated as a percentage of the amount needed to achieve saturation at the same temperature.

The importance of humidity monitoring

Humidity is highly sensitive to temperature and pressure fluctuations in the surrounding area and can quickly change.

High humidity can cause an undesirable level of moisture in the air which can negatively impact a wide range of products as well as creating an uncomfortable environment for people. Increased moisture can damage electronic equipment, manufactured products, structures, encourage the growth of mould and mildew and cause rot.

Low humidity levels can cause excess build up of static electricity, increase the susceptibility of colds and respiratory illnesses and allows viruses and germs to thrive. It can also have adverse effects on plants, wood, paint and other objects that are hygroscopic as their natural moisture levels are decreased in line with the RH.

The aim of humidity monitoring is to ensure the safety of the local environment and allow a quick and correct response to the shifting factors in the surrounding area. Being able to react correctly and quickly can not only save products from unnecessary damage and create a safe environment for humans but it could also be used a cost saving initiative when it comes to air conditioning demand.

Bedford Borough Council

Our Computer Room Air Conditioning (CRAC) units have automatic de-humidification functions. When the humidity becomes too high or too low our CRAC units compensate their settings to adjust the humidity automatically. OmniWatch helps us to ensure humidity levels remain within their expected levels.

Tonal language and humidity

A humans vocal cords contain a pair of mucus membranes that stretch across the larynx. As we speak air is controlled from our lungs and cause the larynx to vibrate. The level of moisture in the air effects the elasticity of our vocal cords and hence have a direct effect on our tonal range.

Recent scientific research has proven that the environment has a direct impact on speech. After studying more than 3,700 languages it was discovered that tonal languages found commonly in Asia rarely develop in dry climates.

Humidity helps bug diversity

Because most bugs are small, humidity increases the opportunity for them to survive. The smaller the bug the more likely it is to dehydrate because it has a larger surface area relative to their whole body size.

Humid nights are especially helpful to moths who make the most of moist climates. A world leading Professor of Entomology at the University of Arizona, Goggy Davidowitz, determined that hawk-moths (Manduca Sexta) can detect a four percent difference in humidity by sensing changes in the evaporation of flower nectar.

The warm, moist atmosphere of a humid environment helps hawk- moths to identify which flowers are higher in nectar than others and as a consequence helps them to conserve energy whilst foraging.
