* 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。

* The YS-17 is an infrared flame detector monitoring the infrared spectral band for specific patterns given off by hot gases. Radiation of flames and fires is sensed using a specialized infrared receiver and then converted to an electronic signal. This signal is compared with a threshold signal and when it reaches the threshold value the module will output a low level.

1 Introduction

Fire Sensor
  • 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. Its detecting angle is up to 60 degrees. Its sensitivity can be adjusted via the potentiometer.

2 Features

  • Standard 3 PIN Interface
  • PCB Dimension(mm): 16 x 24

3 Basic Device Operation

  • The YS-17 is an infrared flame detector monitoring the infrared spectral band for specific patterns given off by hot gases. Radiation of flames and fires is sensed using a specialized infrared receiver and then converted to an electronic signal. This signal is compared with a threshold signal and when it reaches the threshold value the module will output a low level.

5 Compile & Run Test Program

Boot your ARM board with Debian and copy the matrix code: 

$ apt-get update && apt-get install git
$ git clone https://github.com/friendlyarm/matrix.git

If your cloning is done successfully a "matrix" directory will be generated.

Compile and install Matrix: 

$ cd matrix
$ make && make install

Run test program: 

$ matrix-gpio_int

Note: this module is not plug and play therefore before running the module please make sure it is connected to an ARM board.
Here is what you should observe:

Waiting event...
Device[0] value is 1

If a flame is within its detection range it will be detected and an event will be triggered.

6 Code Sample

This Matrix code sample can work with all the ARM boards mentioned in this module's wiki. The name of this code sample is "matrix-gpio_int". Here is its source code: 

int main(int argc, char ** argv)
{
    int i, board;
    int retSize = -1;
    char value[ARRAY_SIZE(dev)];
 
    if ((board = boardInit()) < 0) {
        printf("Fail to init board\n");
        return -1;
    }
 
    if (argc == 2)
        dev[0].pin = atoi(argv[1]);
    system("modprobe "DRIVER_MODULE);
    signal(SIGINT, intHandler);
    if (board == BOARD_NANOPI_T2)
        dev[0].pin = GPIO_PIN(15);
    printf("Use GPIO_PIN(%d)\n", dev[0].pin);
    if ((devFD =sensorInit(dev, ARRAY_SIZE(dev))) == -1) {
        printf("Fail to init sensor\n");
        goto err;
    }
    printf("Waiting event...\n");
    if ((retSize = sensorRead(devFD, value, ARRAY_SIZE(dev))) == -1) {
        printf("Fail to read sensors\n");
    }
    if (retSize > 0) {
        i = 0;
        for (i=0; i<retSize; i++) {
            printf("Device[%d] value is %d\n", i, value[i]);
        }
    }
    sensorDeinit(devFD);
err:    
    system("rmmod "DRIVER_MODULE);
    return 0;
}
