TheDesign ofBased on Single-chip Orchard Ambient
Temperature Detection and Alarm System
Abstract: Temperature is that people in agricultural production often
need to measure and control an amount, and microcontroller-based orchard
ambient temperature measurement and temperature measurement alarm and
alarm system makes more intuitive, accurate, and it is easy to use,
reliable performance advantages. mainly discusses the orchard environment
temperature measurement and alarm processing method and system
configuration. Based on the performance characteristics of digital sensor
DS18B20, using SCM and simple interface circuit a temperature measurement
and alarm system, through the keyboard and LED display digital temperature
display and temperature alarm limit settings. There gives the relevant
application circuit and software programs. The system temperature
measuring range -55 ℃ - +100 ℃ between, its measurement accuracy of 0.1
℃. The system fully meets the orchard temperature measurement and alarm
requirements.
With chip technology and development of semiconductor technology, this
intelligent temperature measurement and alarm technology will gradually
replace the traditional temperature measurement technology, making the
temperature measurement and automation technology towards more intelligent
