i need these for a mushroom greenhouse, so, i need to make the humidity get to around 95-100%
Im quite capable of calibrating these but i need to know if they can set to reliably read out that range, 95-100%, so that every time it is exposed to say, 100%, it reads out 100%, all i really need to know is if or not the humidity in the greenhouse is 100%, this is to enable a fogger. Ideally if it can read the specific value between 85% and 100% RH, i could quantify the amount of water neccesary to deliver to the fogger. SO i guess i either need to be able to reliably read out 100% or reliable and reproducibly read out a value at or above 85% at the very least. if it ends up functioning more like a binary switch then so be it.
I shouldnt allow humidity to drop below 85% though i generally want to keep it at about 95-100%, yet not oversaturate which ends in everything getting wetter than it should be.
But sometimes ill also want it at 90%, for a particular species of mushroom.
which of these sensors would be best suited to the task (with DHT22 id be using 2-3 wheras with the others, only 1)
All thats really important is that theres one value above 85% that i can read with certainty, ideally 100%, but if something else, thats fine too, so long as i know the humidity and temperature i know exactly how much water to nebulize. or if 100% is best, then i can just go until it stops or act based on how it approaches saturation.
for any other value i dont need any real accuracy, just 1 point where i know its reliable.
