A sensor multifunctional Bluetooth food probe is provided; a first sensor is provided at a front end of a probe body tube and configured to measure food temperature; the first sensor is connected to a PCB board and a main control circuit through first and second wires, the probe body tube is provided with a first charging electrode; a second sensor is provided at one end of a handle and configured to measure an environmental temperature; the second sensor is connected to the PCB board and main control circuit through third and fourth wires; the handle serves as an antenna or a second charging electrode; a switching circuit is configured to switch the third and fourth wires to a charging module or a temperature measurement module. In this application, the antenna is externally mounted and has fewer internal wires to reduce interference signals.

Sensor multifunctional Bluetooth food probe

A temperature measurement circuit structure and a temperature probe are provided. The temperature measurement circuit structure includes a first temperature measurement circuit, a second temperature measurement circuit, a charging module, and a switching circuit, the switching circuit is connected to the charging module; a third wire and a fourth wire of the second temperature measurement circuit are connected to a control chip through a PCBA board; a first charging wire of the charging module is connected to the control chip through the PCBA board; in a charging state, the switching circuit connects the third or fourth wire to the charging module and serves as a second charging wire of the charging module; in a non-charging state, the switching circuit disconnects the third or fourth wire, which serves as the second charging wire, from the charging module. By switching the circuit, one wire inside a handle was reduced.
