Whether he used a PLC or PLA unless it is programmed tested and approved by various agencies $$$ and unless the wiring is good for Class 1 Div 2 or whatever is required...
Intrinsicly safe? A very specialized line of work.
Good ESP32 application.
From another engineer. Tell your son that if his wife’s 14 year-old GMC SUV A/C quits to check the clutch cycle switch. I just replaced that on my wife’s barely broken in ‘07 Envoy for $20. Oh, and my kid drove my old ‘99 pickup until he made enough to upgrade a couple of years ago. It had over 280K miles on it.
A local kid, 25 years-old, raises and sells produce as a side gig to his civil engineer job. He is all about technology and labor saving investments. His irrigation is totally automated with ground sensors to control the irrigation system that is programmed for each plant type.

They should not call him names.
The dollar you did not save, you stole from your grandkids!
When you see a gaggle of them together, it is a safe bet that most of them cut their own hair. The wife trims the back.
A young engineer comes into work one morning and is spotted to have two different colored socks on!!!
Not way off, black and dark blue.
Thereafter he was forced into a sock check most mornings.
He was so proud of his solution, he claimed to have dumped ALL of his socks in the trash and purchased a couple of dozen identical black pairs!
No one believes he actually trashed them, just saves them for weekends.
My company is in a related business (otherwise, why go through the pain?).
But the mats are the story that Toyota pushed, but the reality was that the interfaces in the SW were quite suspect. No record in any logs, but when the interface for the various components were evaluated by auditors, there was high probability that the SW interfaces had a defect that could cause ambiguity in determining throttle status.
They would not have paid 4 very large ones for floor mats, when it comes down to the punch. That was their “cover” story. The real story showed up in places, but wasn’t widespread:

PLC is product life cycle in this case, not programmable logic controllers.
He used off-the-shelf smart switches and some cheap temp and humidity sensors. Not much there to patent.
I’ve got that same Z-Wave stuff running in my house for much the same purpose. Except I’m not drying grain — I’m dehumidifying the bathrooms.

Thanks, I will pass it on to him.
I’m not engineer and my family calls me Rube Goldberg re some of my patches, repairs and by passes.
Thanks to YouTube I have found all types of reset buttons for Dishwashers, washing machines about everything in our office with a lot electronic stuff.
2 DIL’s use YouTube all the time, and a couple of my wife’s friends near our age.
We compare notes on the internet,by phone and texting.

Even in their early 20’s, they are frugal and know how to do simple things to fix or patch something.
Re the socks, I had a manager, who had all dark blue/semi black socks, the same ties to go with his same sport coats and slacks and shoes. Topped off with the same white oxford dress shirts.
Too many people use incorrect vocabulary. ‘Cheap’ brings visions of miserly Ebenezer Scrooge, eating gruel in a cold lonely room. In this case, Scrooge might just ignore aeration control and foolishly watch his harvested grain rot.
This farmer / engineer is, instead, frugal in use of his time and money. Say that he buys the commercially offered aeration control at $80k. Something goes wrong, what is his after-sale tech support and at what cost? His own system, built for 1/800th the cost, may have fewer ‘bells & whistles’ but, then again, his install may not need them. Failure of his system is his own responsibility and, like the build itself, costs him irreplaceable time & effort, aka ‘sweat equity’! Still, being the builder, he may find the fix faster that that help desk guy, Steve, in Bangalore (India)!
Just an opinion but I like frugal!
I have one that I’ll bet could put yours to shame for frugality. He never has any money except for the things he wants to do but he isn’t cheap. He always pays his way and I have never seen him turn down someone in need of help.
If he were slaughtering pigs he would use everything but he squeal and he would work on that.
From the article:
Everything is run by the "eWeLink" app, which can tell the outside temperature and humidity. The app connects to a “eWeLink” switch.
The system allows him to set a “scene.” For example, he can have the system automatically turn on when the outside temperature is between 50 and 80 degrees F, or when the relative humidity is between 50% and 70%.
He uses charts for each grain for equilibrium moisture content.
“I look up the desired equilibrium on the chart, and find my desired moisture, and then it shows the temperature and humidity range the fan needs to run at,” he said.
FacePalm. .cn is china so he's a genius dumbass
Farmers to survive have gone really high tech for both the science and the business sophistication. If not, they are put out of business by the corporate farmers such as Cargill and ADM.
On YouTube, look up the channel for Millennial Farmer. It's interesting.:.

Whenever there is a hard job to be done I assign it to a lazy man; he is sure to find an easy way of doing it.

Basically, my wife and I have to tell our adult kids, “Please let us buy lunch or whatever.”
