Description

The HS300x (HS3001, HS3002, HS3003, and HS3004) 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.
