Here is my first overnighter. Added a +-1F hysteresis to the temp so you can see it change back and forth. This did slow the cycles down to about 1 every 30 mins. Humidity still is controlled by the cooling cycle, but it looks close enought to 85%? http://i191.photobucket.com/albums/z84/lovingHDTV/C...

Yes I need to figure out how to code that. Now that I have the other stuff working that is next on my list.

Ideas?

I put in a the water pan from my old ECB and that helped a bit, so I figured "more is better!" and added a 5-gallon bucket. That helped a ton. The temperature is rock solid now, it just doesn't move (to within .5F). The fridge cycling still affects the humidity, and always will, but I can now keep i...

Well here is another picture. I got the PID for the fridge working quite well. I went with a minimum on time of 1 min and a minimum off time of 1 min. This means that the fridge won't turn on and off quicker than that. Turns out that even with the 1 min on minimum it keeps a decent temperature range...

It appears that when the fridge is not running, the humidity increases. You can see this in the plot below. The temperature does not change much at all, so I don't think that is the issue. The humidity just creaps up. Then when the fridge turns back on, the humidity drops. Or is the humidity sensiti...

for clarification. I was not doing anything to try and control the humidity. I was just watching it change as the fridge ran. I was surprised to see the spike in humidity while the fridge was still running. that's all.

OK did my first temperature control test. I'm surprised at how easily it maintained 70 degrees. For my smoker I had to tweak the crap out of the PID values. Not sure why this was so easy, maybe the temp just changes so slowly it worked. Next it humidity control, but I have to wait for some new SSRs....

Initially I just plan to support either heat or cool, not switch over. Being here in TX that will only prohibit working over a small period of time where the weather switches. I do plan to automate the controls to handle switching between the two, which is why I have an internal and external tempera...

I am still working on this. Not being a web programmer this has been a big learning experience. Here is what I have at the moment. This is the graph that displays the temperature, humidity, fridge runtime, humidifier runtime. It will let you keep track of what is happening in the chamber. http://i19...

My meat curing chamber build

A few months ago I started on my journey to make a raspberry pi controller for my future meat curing chamber (a side by side fridge). I've had it running for weeks now and it seems to be working fine in my test mode. Test mode is to sample humidity/temp, handle power failures, sensor failure, send e...

side-by-side fridge as a curing chamber?

Anyone tried to use a side-by-side fridge? I'm not sure if you can remove the center divider. I've a lead on a side-by-side, but don't want to get it if I can't use it.

PH Meter

Has anyone used one of these before? https://www.atlas-scientific.com/product_pages/kits/ph-kit.html I emailed them and they do have a lot of customers using it for dry curing meat. Curious if any of them are here. If so how has it worked out? I'm considering adding it to my raspberryPi project. I'd...
