The geeekus Analog Steam Sensor Module allows you to have a DC voltage output depending on the level of moisture detected across its sensor pads (dry state has a low value;when humidity on the face of this sensor rises, output voltage will increase). This basic sensor module can be used to detect the presence of steam, water, rainwater, moisture, vapour, etc.
This steam sensor module can be connected to the GPIO of a 5V/3.3V microcontroller directly. The analog output voltage will increase when the humidity on the exposed lines on the pcb sensor surface goes up; the more water the more the conductive wires on the module surface will be connected causing a gradual rise in the output voltage.
Note that the 3-pin connector of the module is not waterproof, so do not dip the connector directly into the water!
Specifications:
1.Working Voltage: 3.3V or 5V
2.Working Current: <20mA
3.Range of Working Temperature: －10℃～＋70℃
4.Interface Type: Analog Signal Output
Pin Definition：
S：Signal Output
V：Power Supply(VCC)
G：Ground(GND)
Connection Diagram:
Sample Code:
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 steam is detected (for example of boiled water), a moisture value will be displayed on the serial monitor of Arduino software based on the level of humidity detected.
