| Abstract: |
| Objective To study a method to set the dew point temperature as a control target in the climate environment test. Methods Wet and dry bulb thermometer was selected as the sensor to measure the vapor pressure, and the saturation vapor pressure was used as an important parameter to calculate the humidity, in order to explore an equation for calculating saturation vapor pressure applicable in micro-controller. Then a dew point temperature calculation model was established to obtain the relationship between the dew point temperature and vapor pressure. Results The values of 100 groups of samples in the range of 0-100℃ had small average error in comparison with the values in "Psychrometric Handbook". Conclusion This formula could be applied to calculate the dew point temperature in the humidity test. |
