• Lead Free Status / Rohs Status: Lead free / RoHS Compliant

Note 24: Software-corrected accuracy is accomplished using the method detailed in the Software Correction Algorithm for
Note 25: Every DS1923 device is measured and calibrated in a controlled, NIST-traceable RH environment.
Note 26: Higher accuracy versions may be available. Contact the factory for details.
Note 27: If this device is exposed to a high humidity environment (> 70%RH), and then exposed to a lower RH environment, the
Note 28: All capacitive RH sensors can change their reading depending upon how long they have spent at high (> 70%RH) or low
Note 29: Individual RH readings always include a noise component (repeatability). To minimize measurement error, average as
Note 30: Like all relative humidity sensors, when exposed to contaminants and/or conditions toward the limits of the safe operating
