1 Introduction
- The Matrix-Fire_Sensor module is a flame detector module. It uses the YS-17 flame detector to detect flames or fires. It can detect flames or fires whose wavelengths are between 760nm and 1100nm.
火焰传感器，用于各种火焰、火源探测。可以检测火焰或者波长在760纳米～1100纳米范围内的光源，火焰越大，测试距离越远，探测角度60度左右，对火焰光谱特别灵敏，模块测试灵敏度可通过电位器调节。
Ultraviolet (UV) detectors work by detecting the UV radiation emitted at the instant of ignition. While capable of detecting fires and explosions within 3–4 milliseconds, a time delay of 2–3 seconds is often included to minimize false alarms which can be triggered by other UV sources such as lightning, arc welding, radiation, and sunlight. UV detectors typically operate with wavelengths shorter than 300 nm. The solar blind UV wavelength band is also easily blinded by oily contaminants.

3 Basic Device Operation
- 火焰的热辐射具有离散光谱的气体辐射和连续光谱的固体辐射，YS-17火焰传感器利用红外线对对火焰非常敏感的特点，使用特制的红外线接收管来检测火焰的热辐射，然后把火焰的亮度转化为高低变化的电平信号，再通过比较器与参考阈值电压比较，达到阈值电压时，模块输出低电平。
