| Abstract: | A temperature-humidity measuring instrument based on 8031 microcontroller is introduced. The hardware structure and principle of the software design of the instrument are given. A oscillation circuit consisted by humidity sensitive element and 555 time based circuit is used as changeover signal interface, thus this instrument becomes a system with complete function involving measurement, display and humidity warning. The instrument has a good performance, low price and wide use in many other fields. |
