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); }

Sir ...I connected all and the motor is running...but when I put sensor in the mud or water motor also running it doesn't on or off ...what can I do for this problem plz solve this 🙏

[@amirreza33]

@@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!

[@jonburgmann]

Put a toilet cistern on wall when it needs filling it will do it as the float lowers & a 12vdc solenoid when the dirt become dry it switches on solenoid & allows water to flow from cistern down through solenoid make a ring with small 5-6mm poly garden hose & tee to connect to solenoid output drill some 1mm holes in underside of the poly tube ring (holes face down to soil) when soil becomes damp enough it switches water solenoid off until soil becomes dry again

[@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.

Sir can you please tell me is the green wire connected to the + of the battery or to the - of the battery and did you Connect the - ve of the pump with the relay N/O pin? Great video sir thank you very much

[@TechieLagan]

See the positive negative doesn't matter in the pump which is used in the video.. U just have to connect one wire of the pump directly to the battery and the other wire u have to connect it to the battery but through the relay module... The connection will be same as we do for connecting a switch to any simple circuit...

[@Ahamedraza-1537]

Which battery bro

[@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.

nice project ,but how do we give the power supply to the arduino and to the water pump at the same time? i mean like can we supply the power to the water pump from the board 5v pin ?

[@TechieLagan]
