Introduction

Steam sensor is an analog sensor and can be made as a simple rainwater detector and liquid level switch. When humidity on the face of this sensor rises, output voltage will increase.

Codes

void setup()
{
Serial.begin(9600); //open serial port, and set baud rate at 9600bps
}
void loop()
{
int val;
val=analogRead(0); //plug vapor sensor into analog port 0
Serial.print("Moisture is ");
Serial.println(val,DEC); //read analog value through serial port printed
delay(100);
}

Result

When detecting different degrees of humidity, the sensor will get the feedback of different current value. Shown as the following picture. When the sensor detects the steam of boiled water, the moisture value is displayed on serial monitor of Arduino software.
