Overview

Description

The HS3101-ML1 module enables quick application integration with a standard 4-pin header and a fully calibrated HS3101 relative humidity and temperature sensor. The HS3101 features a hydrophobic membrane protecting it from environmental dust, particles, and liquids. The HS3101 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.

Features

  • RH accuracy: ±1.5%RH, typical (10 to 90%RH, 25 °C)
  • Hydrophobic membrane, IP67 rating
  • 14-bit resolution: 0.01%RH, typical 
  • Fast RH response time: 4 seconds, typical
  • Temperature sensor accuracy: ±0.2 °C, typical (-10 °C to +80 °C)
  • Low current consumption: 1.0µA average (8-bit resolution, 1.8V supply), 24.4µA average (14-bit resolution, 3.3V supply), one RH and temperature measurement per second
  • Excellent stability against aging
  • Very low power consumption
