Capasitive Soil Moisture Sensor V1.2 Sensor Kelembapan for Arduino

New.. Capasitive Moisture Sensor
Sistem capasitive bukan Resitive
Lebih sensitif dari yang sistem resitif
-Include driver op Amp untuk mendeteksi perubahan kelembapan yg kecil

Features & Specifications

1. Supports 3-Pin Sensor interface
2. Analog output
3. Operating Voltage: DC 3.3-5.5V
4. Output Voltage: DC 0-3.0V
5. Interface: PH2.0-3P
6. Size: 99x16mm/3.9x0.63″

Contoh Program Arduino :

const int AirValue = 620;
const int WaterValue = 310;
int soilMoistureValue = 0;
int soilmoisturepercent=0;
void setup() {
Serial.begin(9600);
}
void loop() {
soilMoistureValue = analogRead(A0); //Output sensor ke A0
Serial.println(soilMoistureValue);
soilmoisturepercent = map(soilMoistureValue, AirValue, WaterValue, 0, 100);
if(soilmoisturepercent >= 100)
{
Serial.println("100 %");
}
else if(soilmoisturepercent <=0)
{
Serial.println("0 %");
}
else if(soilmoisturepercent >0 && soilmoisturepercent < 100)
{
Serial.print(soilmoisturepercent);
Serial.println("%");

}
delay(250);
}
