Units CO2/TVOC
-
Hi,
I'm trying the Units CO2/TVOC M5Stack Sick C.I'm just copy/pasting the code from the demo https://docs.m5stack.com/#/en/unit/tvoc
And
eCO2 stays blocked = 400ppm
TVOC stay bloced at 0
H2 moving a bit around 13580Any idea ?
Does not seems to work fine.... I have another device Neatmo measuring CO2. It says it's not 400 but almost 1300ppmCOuld you help?
thanks, -
You need to find the right calibration (baseline) values for your unit, so only initialize it, but do not define a baseline, then you will see a difference. Also it should be clean air in the room, f.e. not smoking with closed windows for days.
for debugging purpose output the current baseline values as well, I think you will see a big difference to the ones in the sample then.

hi,
don't know why but if you set that line n°31 in comment, it seems to work"# tvoc0.set_iaq_baseline(35187, 35502)
while True:you may try to use the sample loop that you find in UIflow_Unit TVOC.
As you can see on the picture below, TOVC/eCO2 can be use in a classroom context and it works fine
I initialized it outside the window and came inside after
