The HS300x series is a highly-accurate, fully-calibrated relative humidity and temperature sensor. The high accuracy, fast measurement response time, and longterm stability, along with the small package size, makes the HS300x 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 HS300x family consists of four devices – the HS3001, HS3002, HS3003, and HS3004 offering RH measurement accuracy of ±1.5%, ±1.8%, ±2.8% and ±3.8%, respectively.
