Humidity resistance changes with humidity_advantages and disadvantages of humidity resistance
How does the humidity resistance change with humidity?
The resistance of the humidity sensitive resistor becomes smaller as the humidity increases.
Under normal circumstances, most variable-value resistors are that when a certain change is greater, its own resistance will become smaller. Just like photoresistors and thermistors, the higher the luminosity, the higher the temperature, and the smaller its resistance.
The advantages and disadvantages of humidity resistance
Humidity-sensitive resistors are made using the principle that humidity-sensitive materials absorb moisture in the air and cause their own resistance to change. The humidity sensitive resistors popular in the industry mainly include: lithium chloride humidity sensitive resistors, organic polymer membrane humidity sensitive resistors.
Humidity sensitive resistors are usually made of organic polymers, such as polyamide resins, polyethylene, or metal oxides.
Advantages: low cost, high accuracy, small size, long-term stability, highly sensitive to humidity
Disadvantages: The resistance of the resistor changes nonlinearly with the change of humidity.
