TEMPERATURE SENSOR, ELECTRONIC UNIT INTERACTING WITH SUCH A SENSOR, AND RELATED METHOD AND COMPUTER PROGRAM

摘要

The invention relates to a temperature sensor (1a) including: a resonant structure (2) for vibrating such as to resonate at a resonating frequency that varies depending on the temperature of the plate; at least one sound wave transmitter (3a) mounted onto the resonant structure (2) such as to make same vibrate at said resonating frequency; a sound wave receiver (4) mounted onto the resonant structure and capable of capturing sound waves propagating within the suspended structure; and connection elements making it possible to connect the at least one transmitter and the receiver to an electronic unit outside the temperature sensor. Said temperature sensor is characterized in that said connection elements include a connector with four contact points comprising first and second contact points for conveying a stereophonic sound signal, a third contact point for providing a mass reference, and a fourth contact point for conveying a microphone signal. Said connection elements are configured such as to connect the at least one transmitter to the first and second contact points and connect the receiver to the fourth contact point. The invention also relates to a method and computer program for measuring temperature using such a sensor and to the outer electronic unit for interacting with such a sensor.
