The HS3103-MC1 module enables quick application integration with a standard 4-pin connector and fully calibrated HS3103 relative humidity and temperature sensor. The HS3103 features a hydrophobic membrane protecting it from environmental dust, particles, and liquids. The HS3003-MC1 is fully coated with HumiSeal for better corrosion resistance. The HS3103 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.
