Core Module for Wireless Sensing System

A core module for wireless sensing system used to receive, process and output a sensed environmental information, including:

• a RF front-end circuit, which is used to receive and process a RF input signal to generate a distance detection signal and a control instruction and power-on signal;
• a power control circuit, which accepts the control of said control instruction and power-on signal to supply a DC regulation voltage;
• an analog front-end detection circuit, which receives said DC regulation voltage and starts the function of receiving a sensed environmental signal that carries said environmental information and output a digital environmental signal;
• and
• a baseband signal processor, which receives said DC regulation voltage to receive said distance detection signal and said control instruction and power-on signal for outputting a demodulation control signal to said RF front-end circuit and outputting a power-off signal to the power control circuit, and receives and processes said digital environmental signal to output an impedance control signal that carries said environmental information.
