摘　　要：设计开发了测量环境温湿度等农田信息的采集仪。在探讨该仪器测量原理的基础上,对该仪器的农田环境温湿度测量模块进行了对比试验和标定,结果表明,农田环境温度的标定值与HOBO数字化温湿度记录计的温度测量值相对误差绝对值的平均值为6.086%;该采集仪环境相对湿度测量的标定值与HOBO数字化温湿度记录计的湿度测量值相对误差绝对值的平均值为6.783%,证明该采集仪可以应用于对环境温湿度的测量。A filed information collection instrument to measure the farmland environmental temperature and humidity was designed.Based on the measuring principle of the instrument,the comparison and the calibration experiment to the collection instrument measureing farmland environmental temperature and humidity have been done.The result showed that the average absolute value of relative error between calibration environmental temperature and measured temperature of HOBO digital measurement is 6.086% and the humidity 6.783%.It proved that the collection instrument could be applied to measurment of temperature and humidity of the environment.
