HS41xx
High-Performance Relative Humidity and Temperature Sensor with Analog Output
The HS41xx series is a highly accurate, fully
calibrated automotive grade relative humidity and
Features
■
Humidity range: 0% to 100%RH
temperature sensor with an analog output. While the
HS410x series comes in a standard package with an
open air inlet, the HS411x series features a
hydrophobic membrane, making it dust resistant and
waterproof with IP67 rating. Both sensor versions,
waterproof and non-waterproof, are available in two
different accuracy classes, HS41x1 and HS41x3.
The MEMS sensor features a proprietary sensor-
level protection, ensuring high reliability and long-
term stability.

■
NIST traceability for relative humidity and
temperature
Integrated calibration using a NIST traceable and
verified production setup that is calibrated to ISO/IEC
17025 standards and temperature-compensation
logic provides fully corrected RH and temperature
values via an analog output. User calibration of the
output data is not required.

The high accuracy, fast measurement response time,
and long-term stability, combined with the small
package size, makes the HS41xx ideal for a wide
number of applications ranging from portable devices
to products designed for harsh environments.
Temperature sensor accuracy: ±0.2°C, typical
(HS41x1, -10 to +80°C)
Very low current consumption: 92µA average
(3.3V supply)
Excellent stability against aging and volatile
compounds
The HS41xx are digital sensors at their core.
Measurements are then converted to ratio-metric
analog output. This makes the HS41xx suitable for
high-noise environment applications.
Highly robust protection from harsh environmental
conditions and mechanical shock
