摘要
本文给出了一种新型光电烟雾探测报警器的设计方案,首先简要介绍了超低功耗、且具有自动采集信号性能的单片机MSP430F2012,然后详细阐述了各硬件模块和软件设计流程。通过采用功耗低、速度快、低成本的运算放大器LM358,硬件与软件设计满足了系统的低功耗要求,实现了烟雾探测报警器的基本功能,且功耗低,性能稳定,实用性强。
A novel optical smoke detector is presented in this paper. Firstly, The microcontroller MSP430F2012 with the characteristic of ultra-low power and automatic sample signal is introduced, and then the hardware module and the software flow are provided. The operational amplifier LM358 with low power and high rate and low cost is chosen. The design of software and hardware has met the low power requirement of the system. The basic function of smoke detection and alarm system is realized. Therefore it has low power and the steady performance and strong practicability.
