# The sensor has the highest accuracy between + 5 °C to + 60 °C and 20 to 80 %RH. If the device is exposed to high humidity for a prolonged period, the measuring accuracy decreases. Prolonged exposure may introduce shift in the sensor reading with a slow recovery time. The data logger must not be exposed to a relative humidity of 100% for longer time.
