In the fields of automotive technology, laundry dryers, household appliances and also in the area of industrial applications, humidity sensors are required to measure humidity for the entire life cycle of the product without recalibration. In addition, stiff price restrictions for these high volume applications that only surface mount sensors can meet the market price requirements.
The KFS140-MSMD is both highly reliable using a resistive humidity sensor and low cost due to its surface mount package. This humidity sensor offers a better signal-to-noise ratio than monolithic integrated sensors and are also characterized by excellent long term stability in continuous operation under rough conditions.
Presently, the MSMD humidity sensors represent the smallest discrete humidity sensor in the world with an excellent price-to-performance ratio.
