AI Technical Summary
Existing wireless food probes are small in size and cannot integrate physical moisture or salinity sensors, making it impossible to accurately detect moisture and salinity in variable temperature environments. Furthermore, the metal at the probe tail causes crosstalk between the radio frequency signal and the temperature measurement signal, and the high-voltage power supply is prone to damaging the internal links.
Using insulated metal tip and metal tube components as detection plates, combined with an internal temperature sensor, and through thermal drift compensation and dual-frequency decoupling model, it can acquire moisture and salinity data in real time, and adjust the ratio of signal acquisition and transmission time slots under different cooking conditions to avoid crosstalk and power consumption problems.
It enables accurate detection of moisture and salinity in variable temperature environments, reduces crosstalk at the probe tail, improves the accuracy of data acquisition and system battery life, and adapts to resource allocation under different cooking conditions.
