摘　　要：介绍热释电红外传感器的工作原理。并且设计了基于热释电红外传感器的控制电路,可实现不接触感应控制,增加了执行时间,光照度宽范围调节等诸多功能,从而使该控制电路能适用于更广泛的对象。实验证明,以上这些方法行之有效。The structure and the principles of pyroelectric infrared transducer are elaborated in this paper. Based on this transducer, a control circuit is designed. This circuit can realize the contactless control with many additional functions, such as adjusting the operating time, the illumination range and so on. The experiment proves that this technique is highly effective and convenient in use.

关 键 词：执行时间 光照度 热释电
