environmental sensor measurement
I am testing a SEN66 and my window is open at the moment.
re: environmental sensor measurement
@JennyFluff what's that cost? pretty happy with my SCL41
re: environmental sensor measurement
@noiob I paid 36,574€ per piece for 5 pieces last week at digikey; now they're 44,89€ at 5 pieces :(
re: environmental sensor measurement
@JennyFluff still a good price for all that data imo. might pick one up sometime
re: environmental sensor measurement
@noiob it seems quite nice. Though NOX and VOC are index (1-500) only; not a quantifiable unit.
Can't use it to measure the outside though, it needs 10 °C minimum for operation.
re: environmental sensor measurement
@JennyFluff yeah I have a zigbee ikea thing with some sensirion voc thing so I'm familiar with the voc index. it's still pretty helpful
re: environmental sensor measurement
@JennyFluff I basically just used their cutoff for "should run an air purifier" for my "open a window stinky" notification (not literally that wording)
re: environmental sensor measurement
@noiob oh yeah true; also could be useful once I have graphs of this.
re: environmental sensor measurement
@JennyFluff oh yeah definitely
tbh it's mostly a "you've just used ethanol to clean something" sensor right now
re: environmental sensor measurement
@JennyFluff I mean if it has a carbon filter it should be able to catch VOCs but it'll be slow. uptake is the best when running it at slow speeds which will obvs take some time to clear a room
re: environmental sensor measurement
@noiob I have one but it's very inefficient for alcohols. I guess that is also due to small molecule size
re: environmental sensor measurement
@noiob indeed, I tested it earlier with IPA. This is something my air purifier is not super useful for
