Abstract
This design is to a micro controller, temperature sensor, buttons and TFT screen for the
framework of digital temperature measuring system.STM32F103ZE chips as the main
controller is adopted, through the single bus temperature sensor DS18B20 temperature
acquisition, temperature information through STM32F103ZE micro controller shown in
TFTLCD module after processing, in order to realize the multi-point temperature monitoring.
This design uses the altogether four DS18B20, that is to say, this system can sampling
temperature of four locations at the same time.With temperature sensor temperature after you
come back, all the temperature display on the LCD panel.On the display function, using the
line chart shows that make the show more intuitive, more powerful.The function of the system,
of course, other also have display, such as alarm temperature will real-time display, through
the peripheral buttons to adjust the limit temperature.This design will also be part of a display
related functional keys on TFTLCD, reduce the peripheral circuit, also increased the
human-computer interaction, make the system more humane, intelligent.The design of the
function is all ready, at the top surface temperature detection.
Keywords: microcontroller,TFTLCD,DS18B20, the temperature measurement
