DS1923
iButton Hygrochron Temperature/Humidity
Logger with 8KB Data-Log Memory
ELECTRICAL CHARACTERISTICS (continued)
(V PUP = +3.0V to +5.25V, T A = -20°C to +85°C.) (Note 31)
Note 23: Reliability studies have shown that the device survives a minimum of 1000 cycles of condensation and drying, but this
product is not guaranteed for extended use in condensing environments.
Note 24: Software-corrected accuracy is accomplished using the method detailed in the Software Correction Algorithm for
Temperature section.
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
device reads high for a period of time. The device typically reads within +0.5%RH at 20%RH, 30 minutes after being
exposed to continuous 80%RH for 30 minutes.
Note 28: All capacitive RH sensors can change their reading depending upon how long they have spent at high (> 70%RH) or low
RH (< 20%RH). This effect is called saturation drift and can be compensated through software, as described in the
Software Saturation Drift Compensation section.
Note 29: Individual RH readings always include a noise component (repeatability). To minimize measurement error, average as
many samples as is reasonable.
Note 30: Like all relative humidity sensors, when exposed to contaminants and/or conditions toward the limits of the safe operating
range, accuracy degradation can result (see the Safe Operating Range graph). For maximum long-term stability, the sen-
sor should not be exposed or subjected to organic solvents, corrosive agents (e.g., strong acids, SO 2 , H 2 SO 4 , CI 2 , HCL,
H 2 S) and strong bases (i.e., compounds with a pH greater than 7). Dust settling on the filter surface does not affect the
sensor performance except to possibly decrease the speed of response. For more information on the RH sensor’s toler-
ance to chemicals visit: http://content.honeywell.com/sensing/prodinfo/humiditymoisture/technical/c15_144.pdf.
Note 31: Guaranteed by design; not production tested to -20°C.
