作物冠层温度与作物的生理状态和后期产量息息相关，监测作物冠层温度对于研究作物生理状态和预测产量具有重要的意义。为此，针对目前商用红外测温仪视场角小、没有在线监测功能等问题，设计了一种大视场、定时通过GPRS 传输数据的冠层温度红外传感器。采用定时启动采集的软硬件设计方法，降低了传感器的平均功耗，在电池供电情况下传感器使用时间达到30天左右。

Crop canopy temperature is inextricably bound to their physiological status and latter production .Monitoring the crop canopy temperature is of great significance to study the crop status and predict the production .Due to the small field angle and inability to on-line monitor , commercial infrared thermometers are not very suitable to monitor crop cano-py temperature .To solve this problem , the paper designed an infrared sensor with wild-field and GPRS translation func-tion.Meanwhile, we use the timing collection method to reduce power consumption of the sensor .The sensor can work continually almost 30 days under the 2000 mAh battery-powered condition .
