Overview

Description

The HS4001 is a highly accurate, ultra-low power, fully calibrated relative humidity and temperature sensor. The MEMS sensor features a proprietary sensor-level protection ensuring high reliability and long-term stability. The HS4001 is fully calibrated and temperature compensated with an I2C digital output.

Features

  • Humidity range: 0% to 100%RH
  • RH accuracy: ±1.5%RH, typical 
  • I2C digital output
  • 14-bit resolution 
  • Fast RH response time: 4 seconds, typical
  • Temperature sensor accuracy: ±0.2°C, typical (-10°C to +80°C)
  • Low current consumption: 0.3µA average (8-bit resolution, 3.3V supply), 0.62µA average (14-bit resolution, 3.3V supply), one RH and temperature measurement per second
  • Excellent stability against aging
