The sensing module includes a material sensing circuit, an operation unit and a signal output circuit. The sensing module generates a frequency sweep signal and sends the frequency sweep signal to the probe to sense a status of a material. The frequency sweep signal is a plurality of signals having different frequencies from each other in a predetermined frequency range. When the frequency sweep signal touches the material, an equivalent capacitance of the material is utilized to generate a reflected signal. The material sensing circuit receives the reflected signal and sends the reflected signal to the operation unit. The operation unit operates the reflected signal to generate a waveform signal to determine the status of the material. The operation unit utilizes an impedance spectrum to determine the status of the material."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sensing apparatus and material sensing method","description":"A sensing apparatus includes a probe and a sensing module.
