Specifications are at 25C, 50% RH and typical VDD. Accuracy ethanol signal Accuracy H signal 2 Figure 2 Typical and maximum accuracy tolerance in % of Figure 3 Typical and maximum accuracy tolerance in % of measured value at 25C, 50% RH and typical VDD. The sensors measured value at 25C, 50% RH and typical VDD. The sensors have been operated for at least 24h before the characterization. have been operated for at least 60h before the characterization. 1 Exposure to ethanol and H2 concentrations up to 1000 ppm have been tested. For applications requiring the measurement of higher gas concentrations please contact Sensirion. 2 ppm: parts per million. 1 ppm = 1000 ppb (parts per billion) 3 90% of the sensors will be within the typical accuracy tolerance, >99% are within the maximum tolerance. 4 The long-term drift is stated as change of accuracy per year of operation. 5 Test conditions: operation in 250 ppm Decamethylcyclopentasiloxane (D5) for 200h simulating 10 years of operation in an indoor environment. www.sensirion.com Version 0.9 August 2017 2/15
