针对高分子湿敏器件在不同的相对湿度下其湿度温度系数不同的问题， 提出了一种基于插值法任意温度下高分子湿敏传感特性的计算原理， 给出在智能化仪器中实际应用的具体方法． 该方法巧秒地把一个三维的问题转化成二维问题，并加以合理地应用插值数学方法， 可以推广应用到存在相似问题的其他类型传感器中 Aiming at the problem that the temperature coefficient of humidity of polymer humidity sensitive device is different under different relative humidity, a calculation principle of humidity sensitive sensing property of polymer at arbitrary temperature based on interpolation method is put forward. The practical application in intelligent instrument The specific method. The method cleverly converts a three-dimensional problem into a two-dimensional problem and applies the interpolation mathematics method reasonably. The method can be applied to other types of sensors with similar problems
