介绍了无线传感器节点的设计与实现，以CC2430芯片为核心，利用烟雾传感器设计电路，并通过无线收发模块与网络协调器和上位机通信达到监控目的。-Describes the wireless sensor node design and implementation, in order to CC2430 chip as the core, the use of the smoke sensor circuit, and through the wireless transceiver module and the network coordinator and the host computer to control the purpose of communication.

单端反激式开关电源具有结构简单、输入输出电气隔离、电压升／降范围宽、易于多路输出、可靠性高、造价低等优点，广泛应用于小功率场合。然而，由于漏感影响，反激变换器功率开关管关断时将引起电压尖峰，必须用钳位电路加以抑制。由于RCD钳位电路比有源钳位电路更简洁且易实现，因而在小功率变换场合RCD钳位更有实用价值。 -Single-ended flyback switching power supply with a simple structure, input and output electrical isolation, voltage up/down range, easy to multi-output, high reliability and low cost, widely used in low-power occasions. However, due to leakage effects flyback converter power switch off when the voltage spike caused by the need to be inhibited by clamping circuit. RCD clamp circuit as a result of active-clamp circuit than the more concise and easy to realize, and in low-power transform RCD clamp occasions more practical value.
