In line humidity sensor

dsabol 18 Jul 2019, 16:13 last edited by

I need to measure the humidity level in an air hose (3/4 in diameter) but I'm struggling to find a sensor that would work.. I've been looking for something that would connect to the end of the hose and measure the humidity of the air that passes through, but I haven't found anything.

Are there better options? Surely this has to exist somewhere...

Thanks

@mfalkvidd Yes, that’s the one.

@YuryPol as far as I know, all licenses require some form of documentation. In all cases I know of, this is documented with the license or on the licenses official site.

@samppa yes, but you saw the little point functions your arduino is very capable of, yes? if you post your attempt at a sketch to control your fan (or even pseudo code) we can certainly help you code it up for Vera.

What about a vibration sensor? At least in my kitchen, the fans do produce a slight vibration to the metal roof thing. They pretty cheap on Ebay, I must try it myself...

@Serg2055 as the name says, openhardware.io is for open hardware. You are allowed to sell PCB units, partially or fully soldered boards, but selling source is not an acceptable option. Please include readable schematic and source of your boards or at least gerbers or bom. For all your boards posted on openhardware.io. Thank you !

That's right @gohan , if you place the "door closed"reed near the floor then only first interrupt should matter, first interrupt should tell you the door is closed. Same for a second reed placed high - the "door open" reed, that would tell you the door is open when interrupted the first time. @McQueen, could be close to you needs ...

@bisschopsr said in BlackCircle Sensor - High "WAF" Temp/Hum. sensor: Hi All, Like the design thinking of this, although an older topic I did manage to get me one of these dishes. After taking it apart, I have one question that came to mind. Is the ventilation in the dish enough for the humity sensor? Is there any experience with that after running this sensor for a while? Thx Ralph Hello, yes I think it's enough, in fact there's much more ventilation than in many commercial sensors which only have a small hole. But it's a good test to make, I'll try to compare to a sensor out of it's enclosure to see if there's significant difference or delay.
