Sensors for measuring humidity in the ambient air generally help in monitoring and saving environmental data. Depending on the model of the humidity sensor, relative air humidity of up to 100% can be detected in the ambient air. A number of humidity sensors are available for selection to be able to use the correct humidity sensor depending on the application. We will be happy to guide you. The sensor elements comprise a laser-trimmed capacitive switching circuit with subsequent signal processing, if necessary. New series, such as HumidIcon of Honeywell have an adequate ASIC and thus allow a multitude of information and options.
