| Abstract: | This paper introduces a hardware construct which is used to measure the Grain Hydro-molecule based on PIC MCU control. It analyzes the test characteristics of humidity and temperature sensor and the method of temperature compensation. Virtual curve fitting meter is applied to perform curve fitting operations on sensor output data. Software is used to perform that nonlinear Calibration. Furthermore,It depicts the PIC MCU' application characteristics and PICC C programme main point, and its main software programme flow is given here. |
