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.

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

S GPIO
V Supply Voltage 5V
G Ground

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.

    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;
