Because seed rod always rotates in process crystal growth

it is difficult to measure crystallize interface temperature in crystal growth process. Aiming at the problem of difficult wiring of rotating seed crystal

a new method is put forward to design a wireless sensor with micro controller unit（ MCU） and PT2262 /2272 wireless transmission / receiving chip and match up with thermocouple

realize wireless measurement of crystal growth temperature

and measurement result can be recorded and stored. It lays good foundation for analyzing crystal growth blemish and improving growth quality.
