Abstract
The invention discloses a dual-probe pork humidity detector, comprising a sensor probe (1), a sensor probe (2), capacitive digital converter (3), a singlechip microcomputer (4), a displayer (5) and keys (6). The sensor probe (1) and the sensor probe (2) are capacitive probes and used for detecting dielectric attributes of sensitive pork and converting the dielectric attributes into capacitance, the capacitive digital converter (3) is used for converting the capacitance acquired by the sensor probe (1) and the sensor probe (2) into digital quantity, which is transmitted to the singlechip microprocessor (4) through an I2C (Inter-Integrated Circuit) interface, processed by the singlechip microcomputer (4) and transmitted to the displayer (5) to be displayed. The main advantage of adopting the two probes is that multi-point measurement can be carried out at the same time, the errors in single-point measurement are reduced, and the reliability is enhanced.
