Hi Riva. I can see the spi pins marked in the documentation. Can you tell me which pin is the analog. Is it pin 4? Thanks.
Assuming your device is the same as this TELAIRE | CO2, HUMIDITY & DUST SENSORS then the datasheet shows pin 4 is the analogue out. FYI pin 10 is TX and pin 11 is RX and the data sheet says 9600 boud if you want to compare to serial. To read SPI your probably going to have to ask the manufactures as you will need register information to do this.
