The HS3003-MC1 module enables quick application integration with a standard 4-pin connector and fully calibrated HS3003 relative humidity and temperature sensor. The HS3003  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 HS3003-MC1 is fully coated with HumiSeal for better corrosion resistance.
