KFS Humidity Sensors
Servoflo Corporation of Lexington, Mass., offers the KFS Series of humidity sensors from Hygrosens of Germany.
The series is a relative humidity sensor using a capacitive polymer to measure humidity. Key features include excellent price-to-performance ratio, good linearity, low hysteresis, compact size, and dew resistance. The KFS Series is also stable against chemical effects.
Measuring only 2 mm x 4 mm x 3.8 mm, the KFS-MSMD is a surface-mount version with a better signal-to-noise ratio then monolithic integrated sensors. As one of the smallest discrete humidity sensors in the world, the KFS-MSMD is priced under $7 for 1,000 pieces. This low-cost sensor is suitable for climate monitoring, HVAC, and other environmental monitoring systems.
