How to make Automatic Plant Watering System using Arduino UNO and Soil Sensor || Techie Lagan

[@TechieLagan]

int water; //random variable void setup() { pinMode(3,OUTPUT); //output pin for relay board, this will sent signal to the relay pinMode(6,INPUT); //input pin coming from soil sensor } void loop() { water = digitalRead(6); // reading the coming signal from the soil sensor if(water == HIGH) // if water level is full then cut the relay { digitalWrite(3,LOW); // low is to cut the relay } else { digitalWrite(3,HIGH); //high to continue proving signal and water supply } delay(400); }

@@khadizayesminnodi8786 I had this problem until I fixed the code void setup() { pinMode(3, OUTPUT); // output pin for relay board, this will send signal to the relay pinMode(6, INPUT); // input pin coming from soil sensor } void loop() { int water = digitalRead(6); // reading the signal coming from the soil sensor if (water == HIGH) { // if water level is low (i.e., soil is dry) then turn on the relay digitalWrite(3, HIGH); // high is to turn on the relay } else { // if water level is high (i.e., soil is wet) then turn off the relay digitalWrite(3, LOW); // low is to turn off the relay } delay(400); } Enter this code, most likely the problem will be solved

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!

[@devanshgupta794]

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.

[@TechieLagan]

[@chanakyashukla5820]

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.
