Hi, BSTRobin. We are considering with making more than 10 prototypes of gas sensors using BME680. Attached is the measurement graph using 3 of them. These three units are placed in a glass bottle and placed in the same environment. This measurement graph is fairly complete, but IAQ Accuracy may remain at 1 for several hours. This device BME680 has strict requirements for power supply ripple, so I asked a question the other day because I was worried about the circuit design. What is the relationship between power supply ripple and IAQ Accuracy?
