Table 4 Recommended humidity and temperature conditions for storing and operating the SGP40. Dew point refers to maximum humidity
allowed at minimum and maximum temperature, respectively.
Figure 3 Recommended relative humidity and temperature for
operating the SGP40. Green area marks conditions for which
humidity compensation has been optimized. Additionally, gray areas
mark operating conditions without using the humidity compensation
feature.
Figure 4 Recommended relative humidity and temperature for
storing the SGP40.
To ensure an optimal performance of the SGP40, Handling and Assembly Instructions for SGPxx Gas Sensors as well as the
Design-in Guide for Integrating SGP4x Gas Sensors need to be followed.
2.4 Absolute Minimum and Maximum Ratings
Stress levels beyond those listed in Table 5 may cause permanent damage to the device. Exposure to minimum/maximum
rating conditions for extended periods may affect sensor performance and reliability of the device.
