Additionally, some of our sensors include Bosch BME680/688 sensors that measure volatile organic compounds (VOC) emitted as gases. The readings from this sensor are in an experimental phase at PurpleAir. Further details about the BME680 are available from the data sheet . How We Measure Air Quality P…
