摘要
热释电红外传感器不但应用于国防军事,而且在工业和民用通信电子电器产品中都得到广泛应用。通过分析热释电红外传感器输出信号的特性,着重对微弱信号的前置放大电路的设计进行了研究,具有一定的参考价值。
Pyroelectric infrared sensor is not only applied to national defense and military,but also in industrial and civilian communications electrical and electronic products have been widely used.A weak signal processing circuit composed of the low-noise amplifiers and the high sensitivity pyroelectric infrared sensor has been designed and established.And the research results have a certain worth for application.
