Product Description of SEN0121 Steam Sensor Module

Steam Sensor Module is a steam 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. this module is used for a simple rain detector. it is also a cheap steam level switch. it also has a touch sensor. this touch sensor based on humidity. The analog output consists of the blue wire. The black wire is for Gound. the red wire is for power wire. its size is 30x20x6mm. its output voltage signal is 0~4.5v(@5v) or 0~3.0v(@3.3v.

Applications:

it is used for a simple rain detector.

it is a cheap steam level switch.

its touch sensor based on humidity.
