keyestudio Vapor Sensor

Introduction

Vapor Sensor is an analog sensor and can make a simple rainwater detector and liquid level switch. When humidity on the face of this sensor rises, output voltage will increase.

Caution: connection parts is non-waterproof, so please don’t put them into water.

Performance Parameters

1.Working Voltage: 3.3V or 5V
2.Working Current: <20mA
3.Range of Working Temperature: －10℃～＋70℃
4.Interface Type: Analog Signal Output
5.Size: 36mm x 20mm
6.Weight:

Pin Definition:
S：Signal Output
+：Power Supply(VCC)
-：Ground(GND

Connection Diagram

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 you detect different degree of humidity, the sensor feedback current value. Shown as following picture, the value is displayed on serial port, when the sensor detects boiled.
