The HS300x-ML1 series module enable s quick

application integrat i on with a standard 4-pin header

and fully calibrated r el ative humidity and temperature

sensor (HS3001, HS 3002, HS3003, and HS 3004).

Integrated calibrati on and temperature-compensation

logic provides fully corrected RH and temperature

values via a standard I2C output. No use r calibration

of the output data is required.
