hey I got this one sensory connected to analog A0 and pump and selenoid on pwm9 on arduino uno. My next big thing is figuring out the programing so I can have 6 sensors and six pumps and selonoids. this is what i got this far on one code for one sensor+pump and selonoid.
int sensorPin = A0; // The input pin for the moisture sensor
int valvePin = 9; // The output pin to actuate the valve
const int dryThreshold = 950; // Set this threshold based upon your sensor tests
// 1023 = bone dry, < 100 totally submerged
const long sampleInterval = 600; // Sample every 10 minutes
const int irrigationTime = 5000; // Duration to let the water flow
boolean DEBUG=true; // Set to true if you want to read output on the Serial port
void setup() {
if(DEBUG){Serial.begin(9600);}
pinMode(sensorPin, INPUT); // Declare the sensor pin as an OUTPUT:
pinMode(valvePin, OUTPUT); // Declare the valve pin as an OUTPUT:
digitalWrite(valvePin, LOW); // Make sure the valve is closed.
}
void loop() {
int sensorValue = analogRead(sensorPin); // read the value from the sensor:
if(DEBUG){
Serial.print("Sensor value: ");
Serial.println(sensorValue);
}
if (sensorValue>dryThreshold){
digitalWrite(valvePin, HIGH); // Open the water valve
delay(irrigationTime); // Keep it open for the irrigation time
digitalWrite(valvePin, LOW); // Close the valve
}
delay(sampleInterval); // wait until the next time to take a reading
}
anyone knows how to add 5 more sensor and pumps to this code.
thanks
