Arduino Water Sensor for Houseplants

This is just a very minimal example on how to use these kind of sensors. I just read a value from an analog pin every 2 seconds and print it out to serial.

These sensors are available very cheap online and are easy to use... So, now my plants go online... :)

My code:

const int analogIn = A0;  int sensorValue = 0;  void setup() {   Serial.begin(9600); }  void loop() {   sensorValue = analogRead(analogIn);   Serial.print("Sensor: ");   Serial.println(sensorValue);   delay(2000); }

And now to something completely... Need to learn how to add a ground plane in Eagle... ;)
