Air quality monitor seems to be working well now. PM readings are generally quite low, as expected, but rises quickly if someone is smoking. In my kitchen the co2 rises quite high at night, around 1500 ppm, and drops down to about 430 with ventilation in the morning. My 3 dogs sleep in the kitchen.

I should probably put this in a new thread but I am calibrating my solar and UV sensors at the moment. Solar readings are quite accurate without any adjustments, maybe a little levelling needed, but UV readings are nearly double what is expected. Do I just adjust the multiplier in the calculation code or spend more time levelling everything?  It's a uvm-30a sensor.

The soil/leaf interface is working great with 4 DS18B20 temp probes.

Thanks,
