High-precision digitized cotton moisture intelligent detector

A high-precision digitized cotton moisture intelligent detector, which fundamentally solves problems of a prior cotton moisture tester, such as complex operation, large volume, inconvenient carry and non visual display, etc. The detector comprises a measure sensor, a reference capacitance, a digital temperature sensor, a one-chip microcomputer, a host computer and a display module, and a technical main point lays in that the detector also comprises a capacitance-resistance pulse converting circuit and an RS485communication module. The detector employs technologies of the capacitance-resistance pulse converting (RC/F) and the RS485communication module to realize whole course digitization of a moisture sensor. The sensor has high working efficiency, no harm to cotton, portability, simple hardware structure, so as to substantially reduce system hardware complexity; and the sensor also has strong functions, high precision and high reliability, so as to substantially raise anti-interference capability of a detecti
