I Became a Genius Engineer

Lee Cheol-woo, president of the startup club (3)

Beyond measuring temperature and humidity, a lot of actual information was needed to control it.

There wasn’t much information available on the Internet, and according to my dad, there were many variables.

So Minseok and I came to my father’s greenhouse farm to investigate.

“dad!”

“Oh, son, are you here? Why did you say you were coming all the way here?”

“Oh, I have something to give you and something to investigate.”

“A gift? An investigation?”

“Uh. I made something this time.”

“What?”

“No, before Dad, the boiler didn’t work, so farming was ruined.”

“……It was.”

“So I’ve been thinking about how I can reduce that damage. So I made this. Voila!”

I took out the House Alert device and the app at the same time and showed it.

“What is this?”

“You can see the temperature and humidity inside the greenhouse on the app. And if the temperature drops or rises above the set temperature, an alarm goes off. If the boiler doesn’t run at dawn or runs too much and the temperature is abnormal, an alarm will go off.”

“oh?”

“I heard from my mother that the insurance company did not properly compensate me.”

“Since there is a reason attributable to it, I won’t give you 100% compensation.”

“So I made it.”

“Really, my son is great. It’s not a lie to say that he made and delivered a program the other day.”

“Oh, it’s real. Didn’t you believe it?”

“Of course I believed it, but I didn’t see it myself.”

“hahahahaha, how about seeing it yourself.”

“It’s great. My son! Great job!”

“hahahahaha. Oh, and I’m trying to sell this.”

“This? No matter how well it will sell? I’m thinking about the price.”

“Um… Minseok-ah, how much did you say?”

“About 500,000 won for 2 sensors including installation fee. If there is no internet, it costs 5,000 won per month.”

“Um…”

“why?”

“Of course it’s nice, but should I spend that money? I hate the monthly cost.”

Is it like that too?

“okay?”

“Well, Dad thinks so, but I don’t know what other people think.”

“Um… Minseok, what do you think?”

“I don’t know either. I have to actually sell it, but there’s no market, so… I have to bump into it first.”

“Don’t worry too much, because there is no risk.”

“Yeah, my son will take care of himself.

“Ha ha ha. It should work well.”

“Let’s install it first.”

Minseok and I went to install the house notification device in the vinyl house. And during the installation, I asked my dad what I would like to control remotely.

“Well, a lot of things are good when you have control.”

“Like what?”

“Can you see this for example?”

Dad said, pointing to the opener next to the greenhouse.

“What is this?”

“Just because it’s a greenhouse doesn’t mean you have to be warm. You use this to adjust the temperature, and if it’s too hot, open it here and lower the temperature.”

When Dad turned on the switch, the motor started to fill the hole next to it.

“Oh? Is this how it works?”

From noble mtl dot com

“Right, how would it be if all the holes were closed like this? It would get hot inside the house, right?”

“huh.”

“How annoying to have to look at this every day.”

“oh……?”

“If something like this automatically opens and closes, that’s great. And look at this too.”

“What is this?”

“This is an automatic watering machine. Hmm… the word automatic doesn’t suit you? Anyway, take a look.”

When I turned on a switch this time, I heard the sound of the motor running and the water started spraying automatically.

“Oh? Water is given automatically?”

“Eh. I turned on the switch, so wouldn’t it be automatic? Well, anyway, it would be great if these things were managed automatically.”

“I’ll take a look for a moment.”

Dad took a closer look at the on and off switch.

No big deal. It was just a 220v switch. When electricity is turned on, the motor operates to give water and open and close the side ventilation window.

The house notification I made was a part that I could control enough if I added an additional module to the device.

“Is that possible enough?”

“Is this possible? How? Is that possible with this little machine?”

“Oh, you have to add an extra module. But it’s not that big, and there’s a relay circuit that electronically controls the 220v.”

“A relay circuit?”

“Uh, there’s something like that. Anyway, just controlling these things would be enough to help with the work, right?”

“yes!”

“Okay. Then I’ll try making it.”

“Really, is that possible?”

“I think it will work. Next week? I’ll be back by next week at the latest.”

“Okay. Minseok only trusts you.”

After talking about this and that, I finished the installation before I knew it.

“Huh~! It’s finally over. It’s harder than I thought. Shouldn’t we raise the installation fee for this?”

“Maybe?”

Minseok and I said, sweating profusely.

“Then let’s see if it’s working well? Dad has something installed here? Turn it on and see.”

I tampered with my dad’s phone and the house notifications turned on the app.

“Oh, I see. 1st house 23.1 degrees. 2nd house 25.1 degrees. Oh, that’s amazing? Wait a minute, I’ll see if the temperature is right.”

My dad, who went to the greenhouse to check the temperature, came out right away.

“That’s right, the temperature is correct. Hey… If this is true, I’ll be able to sleep peacefully at night. Is the alarm going off?”

“That’s right. Set the temperature a little lower.”

Let Dad manipulate the app.

Beep-! Beep-!

A loud siren rang through Dad’s cell phone.

“Ohhh, good, good. This should be a relief.”

“hahahaha. Then use it. We’ll have to go down and think about what to make of it in the future.”

“Yeah, I’m having a hard time. Dad will ask people once.”

“Uh. Thank you.”

A few days later, Cheol-woo’s father was watching TV leisurely in the late evening.

“hahahahaha, that’s interesting.”

“Cheol-woo’s dad! Isn’t it time to leisurely watch TV? Can I not go to the house?”

“Which house and why?”

“No, don’t you remember the last time the boiler didn’t turn on and we burned it all? Ever since then, we’ve gone out every day at dawn to look around, and what’s going on today?”

“No, Cheol-woo installed a house notification this time. If you have it, you don’t have to go out. You can see all the temperatures here.”

“Cheol-woo made that?”

“Uh, Cheol-woo doesn’t talk?”

“I haven’t heard anything?”

“hahahaha, I guess it’s because I’m shy. He’s grown up so much, he makes all those things for my dad.”

“is it so?”

Cheol-woo’s mother looked as if she still couldn’t believe it.

“It’s this app. Take a look.”

Cheol-woo’s father turned on the house notification app and showed it to Cheol-woo’s mother.

“Oh, does this tell you the temperature?”

“Uh, that’s right. Let’s see… The temperature of building #1, huh? 27.9 degrees? Building #2 is 21 degrees, which is normal? Is something broken?”

It was the dawn of late spring, but the temperature had risen abnormally.

and after a while

Beep-! Beep-!

A loud siren rang out.

“warning! warning! The temperature in Building No. 1 exceeded 28 degrees. warning! warning!”

There was an alarm on my smartphone.

“Uh, honey, I think you’ve got some problems? I’ll have a look.”

“Isn’t that broken? How could the temperature rise that much?”

“I’d rather it’s broken. I’ll have to go anyway.”

“Let’s go together.”

Father and mother headed to the greenhouse.

And the father went into the first block of the problem.

“Wow, it’s hot. What is it, why is it so hot?”

A quick look at the cause.

“Honey, what’s wrong?”

“Ah…. This is the boiler.”

“Eh? Boiler?”

“Uh, the switch’s on.”

“Eh? Why is it on? It must have been off?”

“I don’t know, maybe the cat touched it. Maybe something fell and touched it.”

“what the.”

“There’s a lot more of this than I thought.”

Cheol-woo’s father said while turning off the boiler.

“You can just unplug it.”

“Ah… I forgot that.”

“Really. Really, what kind of farming are you doing with that mental head?”

“Uh huh.”

“Okay, let’s go back.”

“Yes. If it wasn’t Cheolwoo, I would have been in real trouble.”

“Seriously, I almost ruined my summer farming.”

“Hu, it’s really great. My son.”

“Really, do you have some iron?”

“This is enough to say I’ve matured. After I went to the army and came back, people changed a bit.”

“We raised one son well.”

In the midst of making an additional module, a guest came to the club room.

“Hey, is this club LF?”

A man in his late 40s wearing a neat suit.

“Yes. That’s right, but what did you come for?”

“Hello. I came here with the introduction of Professor Mansoo Choi. I am Gihwan Kim, team leader of COMMAX.”

I remembered that Professor Mansoo Choi said he would introduce a company and asked me to meet him.

“Oh, yes. Come this way.”

Fortunately, there was no one in the club room.

“I should give you something to drink, but unfortunately I don’t have anything.”

“No. It’s fine.”

“But what made you come?”

“I heard a lot from Professor Mansoo Choi. He said he developed House Alert.”

“yes that’s right.”

“They used our product for the temperature sensor that went into it.”

COMMAX? Oh, come to think of it, it must have been the place that made the temperature sensor.

“Aha? There are all these coincidences.”

“hahahaha. That’s right.”

“The reason we came this time is that we are trying to expand our business to agriculture this time.”

“Expansion of the agricultural business?”

“Yes. I happened to hear about Professor Mansoo Choi. There is a house notification.”

“Ohh. So?”

“Would you like to collaborate with us?”

“Cooperation?”

When the word collaboration came out, I became wary.

Thinking about it now that Blue Light almost handed over CAK’s copyright, it was dizzying.

Minseok also advised me several times because of it.

Are you trying to steal something this time?

“Yes. We have a product we are making now, but we thought it would be nice to add our product to the house alarm.”

“Hmm… what kind of product are you making?”

“It should be quicker to show you. Hold on.”

He pulled out some sensor-like objects from his bag and placed them on top.

“What is this? I think it’s a sensor?”

“Yes. That’s right. First of all, what is this sensor like? It is a sensor that analyzes the components of the soil. And this sensor is a sensor that analyzes the components of the atmosphere. This is a sensor that analyzes the amount of sunlight.”

“……? Yes? There wasn’t a sensor like this on the Internet, right?”

“Yes. That’s right. It’s the product we’re making this time. If we collaborate with this and House Alim, I think some pictures will come out.”

When I went to the farm, I simply thought about controlling the motors. But with these sensors, the story is different.

By analyzing the composition of the atmosphere, you can create an environment suitable for crops. Analyzing the composition of your soil can help you determine which fertilizer to add.

Not only that, but if you have a sunlight sensor, you will know how much light you need to give your crops.

‘Farming alert! and a remote control device’

If you analyze the various information coming from those sensors and explain it to the farmers easily… … . Farmers will harvest very high quality crops.

Another picture started to form in my head.

“Also, we know that our temperature sensors are being supplied to many farms, but I don’t know. If the business goes well, we will secure a sales route.”
