Namely, using optical fiber collimator and a combination of temperature and hygrometer to monitor temperature and humidity need to set the scope of optical fiber collimator placed in the middle of grating, optical fiber end face of the launch optical expansion swept up in a uniform parallel light through the hygrometer, at the receiving end so that the parallel light beam is then focused back to optical fiber end face. This method is its low cost, test results basically meet the requirements to solve the state material reserves, military, scientific research and production units and other inflammable and explosive

articleAbstract=火炸药危险品仓库的温湿度测试一般采用定时人工读数方式，工作量大、不便于管理。针对其不能采用有源设备进行自动化测试、目前国内尚无适用于该环境的相关产品这一问题，提出一种转换方法：利用传统干湿球温度计所显示的温湿度刻度，以光学方法将温湿度计上的温湿度数值变为光强值（光信号），并以光纤发送出去，采用单片机处理。这种无源测试温湿度传感器的实现方法，采用光纤准直器和温湿度计相结合的方式，把需要设定监测的温湿度范围放置在光纤准直器光栅的中间，光纤端面的发射光扩束成均匀的平行光通过温湿度计，在接收端使平行光束再聚焦回光纤端面。该方法成本低廉，测试结果基本达到要求。,
