RENESAS HS3003

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 provides 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 longterm 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.
