The columnar lithium chloride humidity sensitive resistor structure circuit is as shown in the figure. You can wind two parallel palladium leads on the polystyrene cylinder as the electrodes, then you can besmear the alkalization treatment lithium chloride solution on the polystyrene cylinder. Because the humidity sensing membrane can adsorb or release the water molecules to change the resistance value, so we can get the humidity value by detecting the resistance value between the electrodes.
