recommended range, especially at high humidity, may affect the sensor performance. Prolonged exposure to extreme
conditions may accelerate aging. To ensure stable operation of the gas sensor, the conditions described in the document SGP
Handling and Assembly Instructions regarding exposure to exceptionally high concentrations of some organic or inorganic
compounds have to be met, particularly during operation. Please also refer to the Design-in Guide for optimal integration of the
SGP30.
