The SGP40 is Sensirion’s new digital VOC (volatile organic compounds) sensor designed for easy integration into air purifiers or demand-controlled ventilation.
Hi. For polling we use two bytes for the address/command and six for the humidity/temperature/crc input. Is it also possible to work with only a 16-bit address/command, so I could use DMA readout to avoid too much processor work? (The algorithm should be fed with a 1 second readout.)
The measure command always needs the humidity/temperature/crc to be set. If compensation is not needed, you can send the fixed default values, but still the bytes need to be sent.
