Quest for a fully automatized climate
    #7965308 -


Card (Velleman K8055 USB experiment card) ~$50


Honeywell integrated circuity relative humidity sensor ~$20


Sensor cable connected to USB board


Breathing test of sensor with some real basic visual basic programming :smile:


Connecting the fan


Fan test to see if we can control outputs.

We sure can! :mushroom2::drumming::cheer::monkeydance:


Temperature resistor stolen from an old digital thermometer :captain:


And soldered to the back of the USB experiment card


So far everything is running smoothly :smile:


colors to indicate threshold levels + extra black box


two relays to trigger fan and humidifier


soon to be a box. hopefully :smile:

it's up a running now with a threshold margin of around 10 points.
also adds 10 values and divides by 10 to avoid spikes and give a smoother line.

Significantly less usage of humidifier with this setup.

(23:44:13)-Channel 1 = set on
(23:12:58)-Channel 1 = set off
(23:11:01)-Channel 1 = set on
(22:45:46)-Channel 1 = set off
(22:43:32)-Channel 1 = set on

set on = humidifier on, set off = humidifier off



every graph pixel equals 10 seconds.


*to be continued*

OMG ARP DON'T DO IT!  IMS GONNA HAX IT AND MAKE YOUR CUBES TURN INTO PORTS.

Let us know how it goes :smile:

The programming is about done, sorta. Now waiting for my mate to connect the components and stuff, probably on friday :smile:

My experience with humidity transducers is they don't function well above 70%. Perhaps you've found a better one. I work as an electrical engineer in a MS data center. We have a lot of moisture sensitive equipment, and even the $2,000 transducers freak out whenever it rains, and in this part of the world, that's a LOT.

at room temperature, this one is supposed to be very accurate between 0-100%, and stable over 70%. according to specs.

consumer laws are tight here, and it was bought from a reputable place :smile:

so far so good. if a drop would short it out it'll return 0 until evaporation and resume function.

will be keeping the humidity around ~95%, so shouldn't really be a problem :smile:

I've thought about wrapping the transducers in tyvek, but haven't got around to trying it yet. If yours get shorted out with droplets, it might be something to try.

Thanks for your post :thumbup:

Hopefully this sensor will work, if not I'm going to purchase one of those with the heating element.

Allthou I rarely had any problems with condensation from humidity ranging around 90-95%, and regular cheap hygrometers seemed to keep up with the wet/dry bulb

I second the arduino. Good job though.

Was thinking that spores might confuse the sensors as well? You think tyvek will keep them out?

something I thought could be interesting (the co2 sensor)? :tongue:
perhaps it won't work with high humidity.

I suggest taking a close look at the data sheet, since it actually has a graph describing the output of the system over a range of humidity levels. The graph seems to go up to about 85%, which indicates that it's probably not very suitable for this sort of application.

Furthermore, since the humidity range from 85% - 100%RH is unknown, you'll have to perform a static calibration of your sensor to find out E0. This means you need another CO2 sensor with known accuracy & bias & precision error to be able to estimate the true C02 value & use that to calibrate your sensor.

Most likely you don't have that kind of equipment lying around, so the best you'll be able extrapolate the curve to estimate what value you *could* be getting. Ofcourse, since the calibration curve shown in the data sheet isn't linear at higher humidity levels, you really don't know what to expect.
