Abstract
Provided is a method for collecting sensor data using time-domain reflectometry (TDR). A primary device transmits a TDR signal to a first sensor. A reflected signal is received in response to the transmitted TDR signal. The reflected signal is analyzed to determine an impedance of the first sensor. Based on the impedance of the first sensor, a sensor value for the first sensor is determined.
