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... ;)
