Sometimes the powersupply from the relay is not sufficient enough to power the motor pump. In that case, modify the following connection: 1) NO pin of relay-->one end of the motor pump 2) COM pin of relay--> -ve external power supply 3) Other end of motor pump --->+ve power supply. Rest all the video is perfect!
To modify your Arduino code to have a burst of 3 seconds followed by no output for 90 seconds, you can use the `millis()` function to track time. Here's an updated version of your code: ```cpp int water; // Random variable unsigned long previousMillis = 0; const long burstDuration = 3000; // 3 seconds const long pauseDuration = 90000; // 90 seconds void setup() { pinMode(3, OUTPUT); // Output pin for relay board pinMode(6, INPUT); // Input pin coming from soil sensor } void loop() { water = digitalRead(6); // Read the incoming signal from the soil sensor unsigned long currentMillis = millis(); if (currentMillis - previousMillis < burstDuration) { // Burst duration: 3 seconds if (water == HIGH) { digitalWrite(3, LOW); // Cut the relay } else { digitalWrite(3, HIGH); // Continue providing signal and water supply } } else { // Pause duration: 90 seconds digitalWrite(3, HIGH); // Ensure the relay is off during the pause if (currentMillis - previousMillis >= burstDuration + pauseDuration) { // Reset the timer when the pause duration is over previousMillis = currentMillis; } } delay(400); // Optional delay for stability } ``` This code will provide a burst of output for 3 seconds, followed by no output for 90 seconds, and then the cycle will repeat. The `millis()` function is used to keep track of time, and it compares the current time with the previous time to control the relay output accordingly.
good one! but I made some changes in the code and in the system. I replaced the pins and recoded them for the Arduino Nano microcontroller. I found that when the sensor was giving a low signal the relay (motor) went off. That makes no logical and practical point, when soil is already wet why would we want more water to be pumped into the soil? It should be another way around, which means when the soil is found dry by the sensor it should pump the water from the tank to the surface of the soil. For that, I simply changed the code from HIGH to LOW. if(water == LOW) // Line number 9 Also, I directly connected the DC motor water pump to the pin instead of a relay. Using a relay would be overkill if I want to use it for just a small plant. Relay can be useful If I want to trigger a high voltage bigger AC motor with the same system. To maybe water a whole garden, a park, or a field of crops. But very useful watching you in this video encouraged me to finish a project I was working on for more than 6 years from now. Thanks a lot. I made a video too, not a tutorial but of the functioning project. Though I have to think about giving power to the microcontroller, currently I used my battery bank. I'll try to make a permanent and durable setup.
I'm delighted to see the enthusiasm around the code modifications I made! To help everyone understand the changes, I've created a detailed video explaining the process.

For pump you can use 9 volt battery but for Arduino it depends from which socket you are giving power to the Arduino If you are using the power jack then you can give maximum upto 12 volt but if you giving power through the USB cable then you can use power Bank or charger adapter.
I hope this message finds you well. FLow sensing is costly and trickey , I am are writing to provide you with information on the calibration and prediction of flow rate and the time required to dispense water under varying pressure conditions. This knowledge is essential for efficient water management and distribution in various applications. Flow rate is a crucial parameter, and it is influenced by several factors, including the water source, pipeline type, and pressure control mechanisms in place. For consistency and reliability in maintaining pressure, there are options such as utilizing pumps, auto-filling overhead tanks, or employing devices like the Pressure Controllers. To calculate the flow rate and the time needed to dispense 1000 liters of water with a pressure of 3 bar, we've collected the following data: At 2 bar pressure, the tap dispenses 20 liters of water in 1 minute. At 4 bar pressure, the tap dispenses 40 liters of water in 1 minute. Let's begin by determining the flow rates at both 2 bar and 4 bar pressure: Flow Rate at 2 bar pressure: Flow rate = Volume / Time Flow rate = 20 liters / 1 minute Flow rate = 20 liters/minute Flow Rate at 4 bar pressure: Flow rate = 40 liters / 1 minute Flow rate = 40 liters/minute Now, we need to find the flow rate at 3 bar pressure. Given the flow rates at 2 bar and 4 bar, we can assume that the relationship between flow rate and pressure is linear. To estimate the flow rate at 3 bar pressure, we can use linear interpolation. First, we calculate the flow rate increase per bar of pressure: Flow rate increase per bar = (Flow rate at 4 bar - Flow rate at 2 bar) / (4 bar - 2 bar) Flow rate increase per bar = (40 liters/minute - 20 liters/minute) / (4 bar - 2 bar) Flow rate increase per bar = 20 liters/minute / 2 bar Flow rate increase per bar = 10 liters/minute/bar Now, we can find the flow rate at 3 bar: Flow rate at 3 bar = Flow rate at 2 bar + (Flow rate increase per bar * (3 bar - 2 bar)) Flow rate at 3 bar = 20 liters/minute + (10 liters/minute/bar * (3 bar - 2 bar)) Flow rate at 3 bar = 20 liters/minute + (10 liters/minute) Flow rate at 3 bar = 30 liters/minute With a flow rate of 30 liters/minute at 3 bar pressure, we can calculate the time required to dispense 1000 liters of water: Time = Volume / Flow rate Time = 1000 liters / 30 liters/minute Time = 33.33 minutes In conclusion, it would take approximately 33.33 minutes to dispense 1000 liters of water at a pressure of 3 bar. This information is valuable for planning and optimizing water distribution processes in your specific application.

To modify your Arduino code to have a burst of 3 seconds followed by no output for 90 seconds, you can use the `millis()` function to track time. Here's an updated version of your code:
```cpp
int water; // Random variable
unsigned long previousMillis = 0;
const long burstDuration = 3000; // 3 seconds
const long pauseDuration = 90000; // 90 seconds
void setup() {
pinMode(3, OUTPUT); // Output pin for relay board
pinMode(6, INPUT); // Input pin coming from soil sensor
}
void loop() {
water = digitalRead(6); // Read the incoming signal from the soil sensor
unsigned long currentMillis = millis();
if (currentMillis - previousMillis < burstDuration) {
// Burst duration: 3 seconds
if (water == HIGH) {
digitalWrite(3, LOW); // Cut the relay
} else {
digitalWrite(3, HIGH); // Continue providing signal and water supply
}
} else {
// Pause duration: 90 seconds
digitalWrite(3, HIGH); // Ensure the relay is off during the pause
if (currentMillis - previousMillis >= burstDuration + pauseDuration) {
// Reset the timer when the pause duration is over
previousMillis = currentMillis;
}
}
delay(400); // Optional delay for stability
}
```
This code will provide a burst of output for 3 seconds, followed by no output for 90 seconds, and then the cycle will repeat. The `millis()` function is used to keep track of time, and it compares the current time with the previous time to control the relay output accordingly.
This is very easy to understand. Thank you very much 🙏🏾

Let's begin by determining the flow rates at both 2 bar and 4 bar pressure:

First, we calculate the flow rate increase per bar of pressure:

Flow rate increase per bar = (40 liters/minute - 20 liters/minute) / (4 bar - 2 bar)
Flow rate increase per bar = 20 liters/minute / 2 bar
Flow rate increase per bar = 10 liters/minute/bar
Now, we can find the flow rate at 3 bar:
Flow rate at 3 bar = Flow rate at 2 bar + (Flow rate increase per bar * (3 bar - 2 bar))
Flow rate at 3 bar = 20 liters/minute + (10 liters/minute/bar * (3 bar - 2 bar))
Flow rate at 3 bar = 20 liters/minute + (10 liters/minute)
Flow rate at 3 bar = 30 liters/minute
With a flow rate of 30 liters/minute at 3 bar pressure, we can calculate the time required to dispense 1000 liters of water:
Time = Volume / Flow rate
Time = 1000 liters / 30 liters/minute
Time = 33.33 minutes
In conclusion, it would take approximately 33.33 minutes to dispense 1000 liters of water at a pressure of 3 bar. This information is valuable for planning and optimizing water distribution processes in your specific application.

What type of motor pump we use brother either dc or ac, please tell...
See with this relay you can use both....dc or ac only for demo I have used dc. You can use ac also but be careful..
It depends on your relay module
Where does the green wire and red wire connected to the relay module go
They are connected to 5volt supply from a power bank.
@@TechieLagan Can you just connect the wire from the pump to the relay if the board has enough supply of power?
@@TechieLagan can I connect to 9v baterry?
Yes
No mention about battery
sorry for that
@@TechieLagan voltage of the battery??
@@Threya127 Here i have used power Bank for the Arduino and 9 volt battery for the pump
