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.
