問題点があった。In this case, since only one diode can measure the temperature at one location, when there are many locations (measurement points) to be measured, the diodes are required for that number. Moreover, each diode requires two electric wires for applying a current. Therefore, when the temperature at the N point is measured by the diode, there is a problem that the number of electric wires of (N + 1) is required even if the negative electrode side is the common electrode.
