수위 측정용 센서입니다.

1. Product Name: water level sensor
2. Operating voltage: DC3-5V
3. Operating current: less than 20mA
4. Sensor Type: Analog
5. Detection Area: 40mmx16mm
6. Production process: FR4 double-sided HASL
7. Operating temperature:10℃-30℃
8. Humidity: 10% -90% non-condensing
9. Product Dimensions: 62mmx20mmx8mm

 

2. 연결방법

간단히 3핀으로 연결할 수 있습니다. OUT 혹은 S(Signal) 로 표시된 핀을 아두이노의 Analog 핀에 연결하면 됩니다.

Arduino Water Level Sensor Module
5V/3V3 VCC
A5 (any one among A0~A5) OUT
GND GND

 

3. 예제 코드 (스케치)

Analog 핀으로 입력된 값을 읽으면 수위를 알 수 있습니다. 컵에 물을 채우고 센서를 넣어서 테스트 하시면 됩니다. 물을 더 채우면 출력 값이 올라가고, 소금을 녹여도 출력 값이 올라가는 것을 알 수 있습니다.;;

void setup(){
  Serial.begin(9600);
}

void loop(){
  Serial.print("Water level = ");
  Serial.println(analogRead(A5));
  delay(100);
}
