I salvaged a humidity sensor from an old HP laser printer. The number on it is RHI-110D-CA. It has 4 wires. Pins 1 through 4 are Vin, SDA, GND, and SCL respectively. The chip is what I think I have found to be an equivalent of this.
The power source is 3 to 5.5vdc so I am sure I can use it with an arduino. However, I am unsure how to do this. Do specific parts need their own libraries to operate? Can they be simply connected and load a generic sketch and library?
