Description
Raindrop meter sensor measures the amount of water on the surface. Has 2 outputs analog (A0) and digital (D0). The analog output shows the amount of water on the pcb. 0 for very wet and 1023 for dry.
The digital output gives a 0 or 1 and this threshold value can be set with the potentiometer. If the value is below the set threshold the output is 1 is the value above then the output is 0.
Raindrop meter sensor specifications:
– Works on: 3.3V – 5V.
– Based on the: LM393 chip.
– Adjustable via potentiometer.
– 2 indication LEDs.
– TTL-level output capacity: 100MA.
Dimensions:
– Raindrop sensor board: 54x40mm.
– Control board: 30x16mm.
Delivery includes:
– Raindrop sensor board.
– Control board.
– Dupont cable
Arduino code example:
int nRainIn = A1; // A0 naar analoge port 1
int nRainDigitalIn = 2; // D0 naar digitale port 2
int nRainVal;
boolean bIsRaining = false;
String strRaining;
void setup() {
Serial.begin(9600);
pinMode(2,INPUT);
}
void loop() {
nRainVal = analogRead(nRainIn);
bIsRaining = !(digitalRead(nRainDigitalIn));
if(bIsRaining){
strRaining = "YES";
}
else{
strRaining = "NO";
}
Serial.print("Raining?: ");
Serial.print(strRaining);
Serial.print("\t Moisture Level: ");
Serial.println(nRainVal);
delay(200);
}
