| Abstract: | Analysed the resistance characteristic of semiconductor ceramic moisture-sensor, and designed moisture linearization by moisture sensor parallel equivalent circuit. By using the functional extremum analyzing method, the optimal linear moisture area and its realizating conditions of equivalent moisture signal curve have been found out, and some design examples were demonstrated as well. At last, a method of extending its linear area was presented. |
