It is usually measured in combination with the temperature sensor, it is a capacitive polymer humidity sensor located inside a reflective housing allowing air circulation but preventing the incidence of solar radiation.
We have standard models and efficient models for installation in autonomous systems.
The most common are DMA 675 and 685 with natural ventilation and the DMA 667 and 669 with forced ventilation.
In combination with temperature measurement it facilitates the measurement of relative humidity, absolute humidity and dew point.
