摘要
光电传感器技术是利用物体的光效应,通过采集被测物体的光信号,进而转变成电信号用于信号传输以及分析的技术,该技术应用领域非常广,在农业中的应用也有良好的前景。当前农业大棚自动化程度不高,需要大量人手钱对农作物进行监测以及维护,成本较高。光电传感器配合光纤传输以及嵌入式控制,可以对大棚内的光照、湿度以及二氧化碳浓度等进行智能控制,既节约了人力成本,又可以通过科学的方法使大棚内农作物的生长一直处于最优的环境之下。
Photoelectric sensor is a technology that can use the object's optical effect to acquire the object's optical signal, which can be transformed into electrical signals for transmission and analysis of signals. The technology has wide application and exhibits important prospect in agricultural application. At present, the automation level of agricultural greenhouses is not high, which requires a large number of people to monitor and maintain the crops, having high cost. With optical fiber transmission and embedded control,the photoelectric sensor can intelligently control the illumination, humidity and carbon dioxide concentrations in the greenhouse, which not only saves labor cost, but also makes crops in the greenhouse to grow in the optimal environment by scientific methods.
