Humidity sensors/transmitters have a wide range of possible applications:
- Room humidity sensors are used as surface-mounted or flush-mounted devices for monitoring humidity in indoor spaces such as offices, hotels or conference rooms
- In outdoor areas, they are often used in combination with temperature sensors - to protect buildings from moisture damage
- You can easily monitor high rooms (e.g. greenhouses, galleries or museums) using pendulum or flush-mounted humidity sensors (for installation in suspended ceilings)
- Duct humidity sensors are designed for the precise measurement of humidity (and temperature) in air ducts or fans, e.g. in refrigeration, air conditioning, ventilation or clean room technology
Room humidity sensors: well-being and performance
Whether in offices, conference centers, schools or hotels - a pleasant room climate contributes significantly to well-being and performance.
The optimum room humidity is 50 %. This value is also stipulated in the Workplace Ordinance, for example. The employer is obliged to take countermeasures if the value is significantly higher or lower.
If you want to improve the indoor air, it therefore makes sense to check the humidity regularly. This allows you to take targeted measures to maintain optimum humidity levels in the room.
Room humidity sensors reliably measure the Humidity and the air temperature in the room. Some versions also enable the evaluation of air quality (CO2, VOC PM). In this way, humidity sensors support energy-saving and needs-based room ventilation.
Duct humidity sensors: health protection and prevention of mold growth
Duct humidity sensors - like room humidity sensors - reliably measure the Humidity of the supply or extract air in air ducts. This is because air that is too humid or too dry has a direct impact on health. Dry air also causes people's mucous membranes to dry out and thus favors infectious diseases. This is often the case in winter in the fall. In summer, humid air in particular offers pathogens an ideal environment. It also encourages the growth of mold - which in turn is dangerous for both people and the building fabric.
It is therefore particularly important to check the humidity in the ventilation ducts regularly and to take appropriate measures in the event of deviations from the setpoint tolerance.
Pendulum humidity sensor: Ideal conditions for sensitive plants
Most of our crops and vegetable plants are grown in greenhouses. During the growth phase, the plants need special temperatures and humidity to grow optimally. In greenhouses and botanical greenhouses, however, it is often not easy to keep an eye on and therefore control the temperature and humidity at all levels.
In tall glass buildings in particular, it therefore makes sense to monitor humidity and temperature with pendulum sensors under the ceiling or freely in the room. Only in this way can the optimum humidity/temperature be maintained and adapted to the needs of the respective plant species. While tropical plants can tolerate humidity levels of up to 100 %, native plants or vegetables would die or be attacked by diseases.
On-wall humidity sensors: humidity protection in demanding environments
On-wall humidity sensors are particularly suitable for applications with very high humidity levels of 90 % or more. Such high humidity - often in combination with very high or very low temperatures - can be found outdoors, in laboratories or cold rooms as well as in swimming pools and the like.
This humidity can lead to damage to the building structure, mold growth and associated health risks both outdoors (e.g. in underground garages, cellars or stables) and indoors under extreme conditions (sports halls, swimming pools, communal showers, etc.). It is therefore advisable to keep an eye on the humidity and to take countermeasures in good time if limit values are exceeded.
