The Renesas Electronics HS3004 is a highly-accurate, fully-calibrated relative humidity and temperature sensor. The high accuracy, fast measurement response time, and long-term stability, along with the small package size, makes the HS3003 ideal for a wide number of applications from portable to harsh environments. An integrated calibration and temperature compensation logic provides fully corrected RH and T values via a standard I²C output. 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.
