 made capacitive, but did not grow together, in the end, I just measure the resistance with two probes. Well, let it be the temperature of the soil.
All is well, but RS485... Where is it? There were several options, I will describe in the next part, as a result, everything came down to another controller. He also connected the drive of the entrance gate.
4 discrete and 3 analog inputs, 2 relay outputs.
And most importantly, the RS485 gateway is Ethernet.
I would like to talk about some of the nuances from my point of view.
Why RS-485 and not wireless interfaces? Why not wifi?
I don’t remember where already, but I heard such a phrase - where copper can be laid, copper needs to be laid there. As you can see, to implement this system, you must almost completely redo the wiring. So why not lay extra signal wires? Which is better - dead batteries, clogged ether, or good old copper?
Why not an ARM with Linux, but an ancient 8-bit controller? How is the internet of things?
Everything is simple - the principle of reasonable sufficiency. Why use megabytes of memory and Linux to light a bulb? And in any case, the power unit, input circuits, etc. will be exactly the same.
Why not touch screens, custom switches, mobile phones, tablets, voice control?
I believe the interfaces should be consistent. Waking up at night to drink water, I do not want to figure out which of the 5 buttons to press me to turn on the light. I want to press the standard switch, drink some water and go to bed further. I don’t want each of those who come to tell me what needs to be done to turn on the lights in my house. It’s one thing with a tablet to set up an irrigation or lighting schedule, set the limits of permissible voltage for protection, and quite another to turn on the light.
But what about Internet control?
Of course, there is control over the Internet. I can do anything from anywhere within the framework implemented in hardware. But there is one thing - all controllers must be autonomous and perform their basic functions without any network, Internet or other servers. If I forgot to pay for the Internet - I do not want to be left without light. If I have a bad connection at the cottage - I just want to press the button on the controller to turn on the pump and tank. And the irrigation schedule - you can configure it later.
With the iron part, that’s all, in the next, second part, I will describe the server part. And I will show a few more photos of all this in the collection on the example of a couple of projects.
no raspberries and arduin.

Sacramento, California ARCO Arena 10th March 2008 Setlist: Show Notes: - 'Petrified' was over 'Points Of Authority'. 'There They Go' was over the outro. - The band finally did a full, complete setlist again. It seems Chester was fully recovered for this show. - During the break between the two encores, the crowd started chanting for 'Bleed It Out'. The band then came out and played the song, which was pretty cool. - It seems Brad cut his finger at the end of the show. A fan has said that they saw him go up to a camera at the end of the show and hold his finger really close to it. Info taken from - The Linkin Park Live GuideIt’s all about your attitude. People often say this in challenging situations. But 13-year-old Dylan Cash is living proof.
Dylan rolls toward you in his wheelchair with a toothy grin, looking wide-eyed through his wire-frame glasses. His infectious smile makes everyone around him smile too.
His teachers describe him as having a positive outlook on life.
“Despite having personal challenges, Dylan has a positive attitude every day. He is always polite to other students and staff here at school. He really is a pleasure to have in the classroom,” said teacher Amanda Merrell. “No matter what the assignment is, he does his best to complete it without complaining and because he is concerned about his grades and doing well, Dylan attends tutorials before and after school when needed. Other students enjoy working with him because they know that he will be a contributing member to the group and will be easy to get along with.”
A-B honor roll student
The A-B honor roll student said he spends two to three hours a day studying to maintain his grades and would like to become a pediatrician because he likes children. But he is content to be an only child.
“I have a bunch of little cousins. So, I am used to being around kids,” Dylan said. “I don’t want any brothers and sisters. As an only child), I get paid attention to a lot.”
He has two dogs, both Chihuahuas, which he said are fun to play with, but the responsibility of taking care of them both is enough and he would not want a younger brother or sister for that reason either.
Natural at math
Dylan enjoys math, emphatically saying he is naturally good at it. He competed as a media trainer for UIL football. Although his physical challenges do not allow him to participate like some of his peers, Dylan said he serves as the eyes and ears for both the coaches and the players during practices and games.
He said that while his disabilities make him different from the other students, the physical differences are irrelevant.
“They all just go with it. They don’t even care. We are all the same,” Dylan said.
He also enjoys playing basketball, video and computer games and reading magazines. Dylan competed in Special Olympics in basketball, shot put, javelin, and other track events. He placed first in all of the events with the exception of one race, he said.
“I enjoyed it, but I don’t know if I will do it again. There is a lot of waiting around for your turn,” Dylan said.
While some children dream of growing up and leaving the area, Dylan said he always will be a Covite.
“I will stay in Cove because my whole family is in this area. I don’t want to move very far. I want to be close to them,” D.The Netflix series will be available to watch on September 30. If you are not excited yet, here's five reasons why you should be.
Last month at the San Diego Comic-Con, fans were able to get their first look at Luke Cage in his own Netflix series. It was a hit, turning into one of the showstoppers at the convention.
Yesterday (August 9), the show’s first trailer dropped. Arriving on September 30, the show looks to offer something different from other superhero series. Fans and superhero buffs have been waiting for this, but the show looks to be something that a lot of people can enjoy in a binge marathon.
When the first Luke Cage trailer dropped, it presented an image that defied what we are used to. Here was a Black superhero protecting people, walking the streets of Harlem like a regular person. He is shot at in the trailer while shielding someone, the bullets merely ricocheting off him. This clearly resonated with a lot of people. At this time when the Black Lives Matter movement is making America reexamine itself again, “the world is ready for a bulletproof Black man,” executive producer Cheo Hodari Coker stated at Comic-Con.
There are many Black superheroes around, but very few have received solo billing on the cinematic screen. Look at the past 20 years for example: Storm mostly works with the X-Men, Spawn’s popularity faded after the unsuccessful film, and the last Blade movie was in 2004, which was also when the Static Shock cartoon ended. For the most part, Black superheroes have been sidekicks in Marvel films, and now this is changing with the Black Panther movie, which will be released in 2018. 
One of the things that separated Luke Cage, who is being played by Mike Colter, from other heroes is how his identity as a Black person is explored. His powers came from an experiment in prison, making the character resonate with issues like incarceration and the Tuskegee Experiments. Topics such as police brutality and drugs will also appear in the show, adding a welcoming level of depth to the crime fighting. Just as the Jessica Jones Netflix series addressed rape, Luke Cage looks to hit upon racial issues like no other superhero shown before.
The trailer starts off with Isaac Hayes‘ “Walk On By,” which was sampled by the Wu-Tang Clan. But things kick in, literally by a Luke Cage kick, with a Run the Jewels remix of “Heart Is Full.” Ol’ Dirty Bastard‘s “Shimmy Shimmy Ya” was heard in the first teaser, and there’s a lot more of that in the show.
