I dont know rob, I havent opened the sensor to find out, also i dont know if they have altered the firmware of sensor to stop outputting null values if the sensor has no ldr fitted, the sensors output is always rh,Temp,unfiltered co2, filtered co2.

badwheels thats quite a demand from any all in one sensor, the cozir does most of what you need, if you were to have all those separate you would have quite a breadboard and be in wire/lib hell, your project sounds cool though good luck.

latest version I have is 1.03 - see attachment - but it is a long time since I edited in it. there may be some work in progress on some points in it.
Note that the calibration functions must be used careful and do not use them if you don't understand their impact.

If you have comments remarks let us know.

the attachment returns Error 503 Service Unavailable

Do you have code that works on an arm nxp lpc1769 ?

My CO2 readings seem high what's the best way to calibrate this device. I only have outside air to calibrate against.

many thanks
