摘  要：
为了测量作物蒸发蒸腾量实现精确灌溉,必须对影响作物生长的气象因子,如温度、湿度、光照度、风速和气压等参数进行采集。大量研究表明,温度对蒸腾量的影响最为显著,湿度与光照度次之,风速与气压的影响最小[1]。针对上述情况,基于AVR单片机Atmega128、温湿度传感器SHT11、环境光传感器BH1750和SD卡设计一款气象数据采集装置,能够实时地对环境的温度、湿度和光照度进行采集、显示和存储。经试验测试,该装置具有良好的稳定性。

摘  要：
To realize the precise irrigation,it is vital to measure the crops' evapotraspiration and collect some meteorological factors,such as,temperature,humidity,illuminance,wind speed,gas pressure and so on. Numerous studies show that temperature plays the most significant role on the aspect of evapotraspiration,the following is humidity and illuminance,however,the effect that wind speed and gas pressure plays is minimal[1]. According to the above situation,aiming at designing a meteorological data acquisition device based on AVR microcontroller- Atmega128,temperature and humidity sensor SHT11,ambient light sensor BH1750,SD card. This device could real- timely collect and store environmental temperature,humidity and illuminance. The test shows that the device has good stability.
