The HS401x series is a highly accurate, fully

calibrated automotive-grade relative humidity and

temperature sensor with a hydrophobic membrane.

The membrane makes the HS401x dust resistant

and waterproof. The MEMS sensor features a

proprietary sensor-level protection, ensuring high

reliability and long-term stability.

Integrated calibration and temperature-compensation

logic provides fully corrected RH and temperature

of the output data is required.

The high accuracy, fast measurement response time,

and long-term stability combined with the small

package size makes the HS401x series ideal for a

wide number of applications ranging from portable

devices to products designed for harsh

environments.

The HS401x 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 ultra-low power consumption, micro-Watt, make

the HS401x the ideal choice for portable and remote

applications.
