基于单片机体温检测仪系统的设计与实现

In this paper, a temperature detection system based on a single-chip microcomputer is designed to detect human body temperature, display it in digital form, and play the detected human body temperature specific value through the mode of voice playback.

The system is composed of several parts: SCM, sensor, LCD, and voice module. The hardware structure is designed with the microcontroller STC89C52 as the core. It detects the human body temperature through the temperature sensor DS18B20, displays the human body temperature value on the LCD1602, and then plays the detected value through the voice module. . Part of the system software through the software keil C language program development and design, debugging.

The designed electronic body temperature detector has realized temperature detection, digitization, and electronization, which is of great help to the development of future thermometers. The electronic thermometer can gradually replace mercury (toxic element) thermometers, which greatly improves the use value of thermometers, makes readings clear, and reduces Human body damage, safety and environmental protection have further improved the smart life of people.

Keywords: Body temperature detector; Electronic; STC89C52 microcontroller;LCD1602
