The HS411x series is a highly accurate, fully

calibrated automotive-grade relative humidity and

temperature sensor with a hydrophobic membrane.

The membrane makes the HS411x dust resistant

and waterproof. The MEMS sensor features a

proprietary sensor-level protection, ensuring high

reliability and long-term stability.

The high accuracy, fast measurement response time,

and long-term stability combined with the small

package size makes the HS411x series ideal for a

wide number of applications ranging from portable

devices to products designed for harsh

environments.

The HS411x series digital sensor accurately

measures relative humidity and temperature levels.

The measured data is internally corrected and

compensated for accurate operation over a wide

range of temperature and humidity levels – user

calibration is not required.

The HS411x series are digital sensors at their core.

Measurements are then converted to ratio-metric

analog output. This makes the HS411x suitable for

high-noise environment applications.
