Microwave induction drive circuit, alarm and lamp

The invention is applicable to the technical field of electronic circuits, and provides a microwave induction drive circuit. An amplifying circuit is used to amplify and filter microwaves, so that weak microwave signals are not lost and cannot be detected in extreme places and extreme conditions, the detection stability and reliability are improved, and compared with a traditional infrared induction feedback circuit, the drive circuit is higher inreliability. Besides, microwave induction can penetrate through part of non-metal object induction, the circuit is particularly suitable for being installed inside a lamp in a hidden mode, application is wide, and the lamp can be matched with various common lamps to become a microwave induction lamp due to micro power consumption, induction sensitivity and wide application range. 本申请适用于电子电路技术领域，提供了一种微波感应驱动电路，其使用放大电路对微波进行放大滤波作用，使极端场所和极端情况下，微弱的微波信号不至于丢失和无法被检测，增加了检测的稳定性和可靠性，与传统的红外感应反馈电路相比可靠性更高。另外，微波感应可穿透部分非金属物感应，特别适用于隐藏安装在灯具内部，应用较为广泛，再加上微功耗﹑感应灵敏﹑应用范围广，可以搭配各类普通灯具，使之成为微波感
