Can be connected to the Arduino IO Expansion shield directly
Power supply: 3.3v or 5v
Output voltage will increase when the humidity of the sensor surface goes up
Output voltage signal: 0 - 4.5v (@5v) or 0 - 3.0v (@3.3v)
The 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.
