We have 3 BME680 sensors sitting 10cm apart from each other. These are fresh new sensors (no calibration before), being read every 60 secs by using ESP8266 through BSEC library. As you can see from the plot, we get different IAQ readings from these sensors, even when the accuracy is reported to be 3 by all of them (see e.g. the range between hours 1.5 and 2). Any idea why such different IAQ values could be reported by these sensors? Thanks in advance.
