This article will discuss the device of the master from India, which monitors the level of water in the tanks. The system operates on the basis of Arduino and performs monitoring using ultrasonic sensors. Switching the system to another tank is done using the toggle switch on the control panel.

Let's see a short video, on it the master demonstrates the operation of automation.

Tools and materials:
-Arduino Uno R3;
- The tank for water - 2 pieces;
-Buzzer;
-Ultrasonic sensor - 2 pcs;
-LCD display 16x2;
-Plastic box;
-Tumbler;
Relay 6v / 5A;
- ULN2003;
- Red LED -2 pcs;
-LED yellow - 2 pcs;
-LED green - 2 pcs;
-The wire;
-12V power supply;
-Bread board;
-Resistor -220 Ohm;
-Fasteners;
-Plastic;
-Variable resistor - 10 kOhm;
-Stripper;
-Nippers;
-Soldering iron;
-Glue gun;
-Metal box;

Step One: Scheme
Pre-assemble the module according to the scheme.

Step Two: Code
Loads the code.

The code

#include
#define led 13
#define led2 12
#define led3 11
#define led4 10
#define led5 9
#define led6 8
#define trigger 18
#define echo 19
#define motor 17
#define buzzer 16
Liquid Crystal lcd (2,3,4,5,6,7);
float time = 0, distance = 0;
int temp = 0;
void setup ()
{
lcd.begin (16.2);
Serial.begin (9600);

pinMode (echo, INPUT);
pinMode (motor, OUTPUT);
pinMode (buzzer, OUTPUT);
pinMode (led, OUTPUT);

pinMode (led5, OUTPUT);
pinMode (led6, OUTPUT);
lcd.print ("Water Level");
lcd.setCursor (0,1);
lcd.print ("b Indicator");
delay (2000);
}
void loop ()
{
lcd.clear ();
digitalWrite (trigger, LOW);
delayMicroseconds (2);
digitalWrite (trigger, HIGH);
delayMicroseconds (10);
digitalWrite (trigger, LOW);
delayMicroseconds (2);
time = pulseIn (echo, HIGH);
distance = time * 340/20000;
lcd.clear ();
lcd.print ("Water Space In");
lcd.setCursor (0,1);
lcd.print ("Tank is:");
lcd.print (distance);
lcd.print ("Cm");
delay (2000);
if (distance & lt; = 78)
{
digitalWrite (led, HIGH);
}
else
{
digitalWrite (led, LOW);
}
if (distance & lt; 65)
{
digitalWrite (led2, HIGH);
}
else
{
digitalWrite (led2, LOW);
}
if (distance & lt; 52)
{
digitalWrite (led3, HIGH);
}
else
{
digitalWrite (led3, LOW);
}
if (distance & lt; 45)
{
digitalWrite (led4, HIGH);
}
else
{
digitalWrite (led4, LOW);
}
if (distance & lt; 28)
{
digitalWrite (led5, HIGH);
}
else
{
digitalWrite (led5, LOW);
}
if (distance & lt; 15)
{
digitalWrite (led6, HIGH);
}
else
{
digitalWrite (led6, LOW);
}
if (distance & lt; 15 && temp == 0)
{
digitalWrite (motor, LOW);
digitalWrite (buzzer, HIGH);
lcd.clear ();
lcd.print ("Water Tank Full");
lcd.setCursor (0,1);
lcd.print ("Motor Turned OFF");
delay (3000);
digitalWrite (buzzer, LOW);
delay (3000);
temp = 1;
}
else if (distance & lt; 15 && temp == 1)
{
digitalWrite (motor, LOW);
lcd.clear ();
lcd.print ("Water Tank Full");
lcd.setCursor (0,1);
lcd.print ("Motor Turned OFF");
delay (5000);
}
else if (distance & gt; 70)
{
digitalWrite (motor, HIGH);
lcd.clear ();
lcd.print ("LOW Water Level");
lcd.setCursor (0,1);
lcd.print ("Motor Turned ON");
delay (5000);
temp = 0;
}
}

Step Three: Testing
Checks the operation of electronics.

Step Four: Control Panel
The master makes a shield from a metal box. The front panel will be covered with plastic. Inside the box, it makes holes for Arduino fasteners and circuit boards.

Step Five: Assembling the Control Panel
Solder wires to the LCD pins. In plastic makes a hole for the display. Fixes the display.

According to the scheme electronic details on the board.

Installs LEDs on the front panel.

Sets the switch.

Sets the buzzer.

Installs and connects Arduino.

Step Six: Verification
After installing the electronics, the master conducts testing. To do this, he simply raises the ultrasonic sensor above the floor.

Seventh step: installation of the front panel.
Fastens the front panel.

Step Eight: Ultrasonic Sensor
The sensors are fixed by the master on plastic boxes.

Step Nine: Information Stickers
Makes and sticks information stickers.

Step Ten: Sensor Installation
Secures ultrasonic sensors inside tanks.

Now it remains to fix the shield and conduct tests in real conditions.

Well, we simply have no choice! The truth began to appear imported beef, at the price of my daily earnings per kg ...

When frying - no smell or taste!

They call it "bacon" for it and practically no one buys it. Not meat, but some kind of surrogate.

Premixes are fed. Rather, feed them + mode. The chicken begins to rush at 3 months, by 10 - 12 the peak of egg production is passed. So are broilers and pigs.

And now we have started to appear modern pig farms, I don’t know how they are fed there (and what they are injected with), but they grow like yeast and there is no fat at all, meat is immediately under a thin skin ... When frying - there is no smell or taste!
I asked a friend of the saleswoman (who sells meat in the market) a village pork. He says that if someone occasionally brings it, they themselves, among themselves - into a fight, pay more than they sell!

How is a float with a magnet worn on a test tube with a reed switch worse?

And in the “pre-Hydrophoric era”, in my attic was a cube tank made of stainless steel for water supply. And on top of it is a float from the toilet tank of the old system (wall mounted. Remember that one on the long horizontal lever?) So, I lengthened the wire lever and bent it down so that the device itself would stand on top. And instead of the valve, I put a “microtumber switch” (“micro” - at that time!)))) Remember these brown buttons in an ebonite case?). So he turned on and off the "Stream" in the well through the relay!
The relay, by the way, was picked up from something automatic on a pig farm. The control magnet was also at 220. And I was sickened to listen to the questions "Why the relay, you fool! Directly put the pump through the button!))))

(Young people, thanks to the “Scoop - suck” artificially artificially imposing opinion, probably don’t know that there was a very high level of automation on livestock farms in the 70s - automatic feed dispensers that walked on rails, refueled from an automatic cooking station, distributed the feed operated by operators ... And then the conveyors pulled out manure. And even for driving pigs from place to place, there were electric racers with a specially selected level of electric shock. (Whoever drove the pigs knows that sometimes it’s simply impossible astavit go normal a switch - in the fat it does not hurt) .....!
And then Misha Gorbachev came with his "perestroika" and everything collapsed .... And the piggies again began to drag bags with compound feed and shovels on the hump to clean the shit! (((

If implemented correctly (and not as done here), such a device has certain advantages: the ability to quickly change the pump on and off levels, the ability to indicate the current level and transmit the value remotely.
Another thing is that the reed switch is much more reliable.

I’ve completely stupefied in my old age! I can not catch the point, why make a garden? How is a float with a magnet worn on a test tube with a reed switch worse?

I wonder how long the sensors will work in a humid environment.

Until the glue that the author flooded the modules falls off.))

I wonder how long the sensors will work in a humid environment. And yes there is no full control. Not thought out.

Mysterious item. )))
1. Level control in only one tank, that is, there is no full automation. And this is if Arduino has heaps of entrances.
2. Each level gradation (High, Medium, Low) is divided into two more sublevels. The meaning of this decision is unclear, unless useful for illiterate staff. Although, India - it is such an India.))
