The temperature measurement device designed in this paper is mainly aimed at low-cost and low-power application requirements. It uses the temperature sensor embedded in the MSP430 microcontroller and a simple LED light or buzzer to realize temperature data collection and over-temperature alarm functions. In particular, in view of the insufficient accuracy of the temperature sensor embedded in the MSP430, this paper also designs a method using piecewise linear regression to compensate and correct the temperature data measured by the temperature measurement module inside the MSP430, and obtain a temperature value that can meet actual needs.
