Description
The HS300x series is a highly accurate, fully calibrated relative
humidity and temperature sensor. The MEMS sensor features a
proprietary sensor-level protection, ensuring high reliability and
long-term stability.
Integrated calibration and temperature-compensation logic pro-
vides fully corrected RH and temperature values via a standard I2C
output. No user calibration 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
HS300x series ideal for a wide number of applications ranging from
portable devices to products designed for harsh environments.
The HS300x 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.
Typical Applications
Climate control systems
Home appliances
Weather stations
Industrial automation
Medical equipment
Automotive cabin climate control
