The invention provides a wireless temperature measurement method and cookware. A temperature measurement device and an emission device are controlled for start according to whether electric potential difference exists between any two points on the cookware, when the temperature data of the cookware is sent to an induction cooker, the electric potential difference exists between any two points on the cookware as long as the induction cooker works, and thereby timeliness and accuracy for sending the temperature data of the cookware to the induction cooker are improved.
