| Abstract: | The current_voltage ( I_V ) characteristics of humidity sensors against low and high humidity are measured and their electrical conduction mechanism is analyzed by measuring data. The results show that their major charge carriers are electrons in low humidity , but their major charge carriers are charge ions in high humidity. |
