Design of UV Flame Detector Based on STC SCM

摘要:

介绍了一种基于STC单片机的紫外线火焰探测器。紫外传感器采用OSRAM公司的SFH530-R,设计了传感器信号处理电路获取火焰信号的闪烁频率及其辐射的紫外线强度,通过判断传感器输出交流量的频率及幅值来识别火焰,将直流量转换成0~5V电压信号输出指示火焰强度。

Abstract:

This paper describes a UV flame detector based on STC microcontroller, the UV sensor is SFH530-R from OSRAM Company, a sensor signal processing circuit is designed to obtain the flame’s flicker frequency and its ultraviolet radiation intensity, by determining sensor output AC frequency and amplitude to identify the flame, and converted the DC signal into the voltage signal output 0~5V to indicate the flame intensity.
