Introduction

The HS401x series is a highly accurate, fully calibrated automotive-grade relative humidity and temperature sensor with a hydrophobic membrane. The membrane makes the HS401x dust resistant and waterproof. 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 long-term stability combined with the small package size makes the HS401x series ideal for a wide number of applications ranging from portable devices to products designed for harsh environments. The HS401x 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. The ultra-low power consumption, micro-Watt, make the HS401x the ideal choice for portable and remote applications.
