Abstract
The utility model discloses a digital thermometer, which is characterized by comprising a temperature sensing module, a single chip microcomputer control module and a temperature display module. An output end of the temperature sensing module is connected with an input end of the single chip microcomputer control module, and an output end of the single chip microcomputer control module is connected with an input end of the temperature display module. The temperature sensing module selectively adopts a thermistor, and the single chip microcomputer control module is an MC80F0708 single chip microcomputer. The digital thermometer is low in cost, flexible in temperature measurement, and wide in application scope.
Description
Technical field
The utility model belongs to sensor and electronic technology field, relates to a kind of digital thermometer.
Background technology
Traditional thermometer measure precision is low, the reading inconvenience.The research and design digital thermometer not only helps in the industrial and agricultural production the real-time detection to temperature, and the digital thermometer intuitive display, detects stablely, and advantage such as antijamming capability is strong is a kind of very desirable detection and control tool.In today of scientific and technical develop rapidly, the modern temperature thermometry is compared with traditional temperature measurement technology, and modern temperature thermometry major advantage is the measuring accuracy height, and speed is fast, and stability is good.At present in the world the novel temperature measurement technology just from analog to numeral, develop to intelligent, networked direction by integrated.
The utility model content
The utility model wants the technical solution problem that a kind of digital thermometer is provided, and has convenient reading, and temperature-measuring range is wide, the thermometric characteristic of accurate.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be:
A kind of digital thermometer is characterized in that, described thermometer is made up of temperature sensing module, single chip control module, three modules of temperature display module.The output of described temperature sensing module links to each other with the input of single chip control module, and the output terminal of described single chip control module connects the input end of temperature display module.
Described temperature sensing module is selected thermistor for use.
Described single chip control module is selected the MC80F0708 single-chip microcomputer for use.
The beneficial effects of the utility model have:
The utility model is compared with traditional thermometer, has convenient reading, temperature-measuring range is wide, thermometric is accurate, and its output temperature adopts numeral to show that this CONTROLLER DESIGN is used modern single-chip microcomputer 80F0708, temperature probe uses thermistor, be total to anode LED charactron with 4 and transmit data, realize that temperature shows, can accurately reach above requirement with serial ports.Have with low cost, thermometric is flexible, applied widely, intuitive display, detection is stable, antijamming capability is strong characteristics.
Description of drawings
Fig. 1 is the system design The general frame of the utility model embodiment 1.
Embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Embodiment 1:
As shown in Figure 1, this digital thermometer comprises temperature sensing module thermistor, single chip control module MC80F0708 single-chip microcomputer, temperature display module composition; The output terminal of described temperature sensing module thermistor links to each other with the input end of single chip control module MC80F0708 single-chip microcomputer, and the output terminal of described single chip control module MC80F0708 single-chip microcomputer links to each other with the input end of temperature display module.
The principle of work of this digital thermometer is as follows: as shown in Figure 1, use the temperature-sensitive effect of thermistor, temperature signal is detected, and convert the temperature signal that detects to voltage signal, send to single chip control module MC80F0708 single-chip microcomputer, the MC80F0708 single-chip microcomputer is come the voltage signal acquisition that the thermistor that receives transmits, A/D change-over circuit by inside converts the voltage signal of simulating to digital signal, digital signal is carried out data processing, temperature signal with numeral sends to the temperature display circuit demonstration then, temperature display circuit shows temperature value by time-sharing multiplex, realizes the digital measurement and the demonstration of temperature.
