| Abstract: | It is introduced an environment temperature and humidity detector in library based on the AT89C52 microcontroller. The hardware circuit including temperature detecting circuit, humidity detecting circuit and LCD display circuit are designed and realized. The comparison of the measuring data by the new on-site verifying method and other measuring methods is given. The result shows that the measurement precision of the temperature and humidity are respectively ±5 ℃ and ± 1% RH. The system based on the proposed method can meet the on-site environment test requirement. This device has obvious advantages such as reliable performance, simple hardware, cheap price and good stability. |
