Automatic Irrigation DIY Kit Self Watering System with Capacitive Soil Moisture Sensor 1 Channel 5V Relay Module and Water Pump + 1M Vinyl Tubing for Garden Plant Flower Herb Potted

This is the best kit for this on Amazon. Great price all the parts worked. This is great from someone that just got into audrino and got through some of the tutorials for coding. Remeber you need a Uno or equivalent to get this work also you need the wires to hook this all up.(usually provided in other kits, I have a ton) Audrino is very flexable so you can set this up multiple different ways. I used a breadboard but you can set it up without it. 10-15 Lines of code and had this up and running. Great seller, great price, fast shipping. I only have good things to say about this.Update:This is the best parts kit on amazon for working parts to get this work.If you don't know how to code basic code in sketch don't buy this as this isn't for one that has no clue how to code in arduino at all. This is for people that need the parts in a convenient listing i am a novice. There is no tutorial hand holding for the code side. This is for people that can figure out basic code and pins(plenty of videos) You can ignore the reviews by people saying no instructions as they have no idea what they bought. They wanted the seller to provide the code to pull this off which is not what they listed as it depends on the parts they already own. Anyway this kit is prefect because they sent me all working parts, if your complaining about anything else its your fault. Great seller.

This came super fast as always I've played with it alittle so far and I'm very happy with the quality but most of all I'm extremely excited at just how power the pump is. I got it as a test with the thinking a much bigger pump would be necessary but this one is more then strong enough. I'd definitely recommend it.

The directions are a bit confusing for someone who is an amateur at Arduino, but they can be figured out with some google searches and common sense. The code provided has a few errors in it, so here is the code that worked for me. One can just copy and paste it into the Arduino IDE.const int relayPin = 2;const int sensorPin = A0;float sensorValue = 0;void setup() {// put your setup code here, to run once:Serial.begin(9600);//begins communication with serial monitorpinMode(relayPin, OUTPUT);//sets pin 2 to outputpinMode(sensorPin, INPUT);//sets pin A0 to inputdigitalWrite(relayPin, HIGH);//turns on relay, in turn turning on pumpdelay(500);//runs pump for 1/2 second}void loop() {// put your main code here, to run repeatedly:Serial.print("MOISTURE LEVEL: ");//prints "MOISTURE LEVEL: "sensorValue = analogRead(sensorPin);//sets "sensorValue" to input value from A0Serial.print(sensorValue);//prints moisture levelif(sensorValue>750){digitalWrite(relayPin, HIGH);//if moisture level is above 750, turns off pump}else{digitalWrite(relayPin, LOW);//if moisture level is not above 750, turns on pump}Serial.println();//prints new line for spacingdelay(1000);//waits 1 second before re-checking moisture level}//Remember to select "tools>board" and "tools>port" before uploading code

In testing the pumps this is what I discovered.At 3.3V the inrush is about .11 ah(111 mah) and at 5.0V the inrush is .27ah(270mah). This is well above what an Arduino can put out through any of its output pins.Inrush for those who don't know is the additional amperage that a DC motor will draw when starting. It takes more amps to get going than to sustain.With that being said these pumps will almost certainly need external power. I am no expert(I'm actually a novice at best), but in my testing, I was not able to get the pumps to come to life from my Arduino, only from my bench power supply. I suggest everyone looks into a motor controller as well. They are not expensive and are really easy to use. I only give it 3 stars since no motor controller was included. If someone shows me how to make these run just from the Arduino power its a 5 star from me.The capacitive soil moisture sensor is simple, easy to use, and worked fine. I'm not sure if they require calibration or anything, but even if it isn't super accurate it works for my purposes.

Pump died with extremely limited use. 30 seconds a day for like 6 months…

If you like to start on irrigation automation, this is the right kit for you! Just plug in to the arduino or other MCU kits, set your parameters and you’re good to go!

Bought for a class project great for beginners

i bought this kit to use some of its parts for a fire alarm and I ended building both the alarm and the irrigation system. Worked perfect with my Arduino UNO and it's still operational with my aloe plant
