HS4003

HS4003 is a HS400x series high performance relative humidity and temperature sensor with digital output. This is a highly accurate, fully calibrated automotive-grade 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 long-term stability combined with the small package size makes the HS400x series ideal for a wide number of applications ranging from portable devices to products designed for harsh environments. Application includes climate control systems, instrumentation, home appliances, weather stations, building automation, HVAC systems, medical equipment, data logging systems.
