KY-026 Flame Sensor


  • Sensor for flame wavelengths between 760 nm to 1100 nm infrared
  • 60 degree angle of detection
  • Two outputs mode:
    • AO: analog output, real-time output voltage signal on the thermal resistance;
    • DO: when the temperature reaches a certain threshold, the output high and low signal threshold adjustable via potentiometer;
  • Working voltage: DC 3V – 5.5V

Instructions for use:

  1. The flame sensor flame most sensitive to ordinary light is also a reaction, generally used as a flame alarm purposes.
  2. The output interface can be directly connected to the microcontroller IO port.
  3. With the flame sensor to maintain a certain distance, so as not to damage the sensor temperature, the flame of a lighter test distance 80cm, for the greater flame, the farther the distance test.
  4. Analog output and the AD conversion process, can achieve higher accuracy.
