Abstract: A temperature sensor includes a base for mounting to a part to be sensed. A temperature sensitive element is mounted to the base. A circuit board is mounted to the base. The temperature sensitive element (2) is electrically connected to the circuit board. The temperature sensor eliminates the conventional structure of mounting a temperature-sensitive element on a circuit board, but separates the temperature-sensitive element from the circuit board so as to be located as close as possible to the sensed component.

Abstract: The present disclosure pertains to a wireless temperature sensor and a communication method thereof. The communication method may include collecting temperature data at a first operating frequency and determining whether the temperature data is within a predetermined threshold range. When the temperature data is within the predetermined threshold range, the method may include transmitting the temperature data to a temperature data receiving device at a second operating frequency by broadcasting without establishing communication connection with the temperature data receiving device. The first operating frequency can be greater than the second operating frequency.
