SNAS678C May 2018 – July 2021 HDC2080
Long exposure outside the recommended operating conditions may temporarily offset the RH output. To maintain the highest accuracy, the recommended humidity operating range is 20 to 80% RH (non-condensing) over 0 to 70°C. Prolonged operation beyond these ranges, particularly high RH and high temperature, may shift the sensor reading with a slow recovery time.
When the sensor is exposed to wider humidity and temperature conditions for a short period, Figure 11-1 shows the typical relative humidity accuracy across combinations of temperature and relative humidity.
