| Abstract: | This paper presents a method to measure the multipoint temperature of a rotaung object. The measurement circuits comprise a stationary part and a rotating part. The rotating circuit is widelessly powered by magnetic induction, which can output a train of temperature PWM light pulse. A programmed MCU transfers the PWM pulses into temperature data, which can transmitted through serial communication. |
