1 Introduction
- 模块Matrix-Fire_Sensor是一个火焰传感器模块，该模块使用YS-17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。
2 Features
- Standard 3 PIN Interface
- PCB Dimension(mm): 16 x 24
- Pin Description:
| Pin | Description |
| S | GPIO |
| V | Supply Voltage 5V |
| G | Ground |
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。
