Comment on The Inside of Sensirion's SCD4x
Sal@mander.xyz 5 days agoThe CO2 has not proven too valuable because the humidity controller refreshes the air before CO2 builds up. But the humidity sensor is quite handy. I made a simple humidifier and it gets triggered by a raspberry pi over Zigbee when the humidity drops below 85%.

Sure. It’s just that I determined the same effect could be achieved by a preprogrammed cycle of ventilation and misting - no closed loop needed, as the conditions in the cultivation chamber do not vary enough to warrant the setup.

That is true. To me, the sensor data in itself is of value because I am interested in learning about, for example, whether the CO2 emission changes while the fruiting happens. But it is definitely not necessary for achieving good results. I see it more like a hobby on top of a hobby. Hobby stacking!

Yes, same here. As I said, it was quite interesting and I did it for the same reason, to combine interests.
