This is a steam(water)sensor from DFRobot. This steam sensor can be connected to the Arduino IO Expansion shield directly.The output voltage will increase when the humidity of the sensor surface goes up. Notice:The new version of analog sensor port pin mapping has been changed as the following two features.

Warning: The connector is not waterproof, please be careful not to put the connector directly in water.
