Flame sensor 5mm IR Diode


4 in stock



Flame thermal radiation has the discrete spectrum of gas radiation and continuous spectrum of solid radiation, YS – 17 flame using infrared sensor on the characteristics of the flame is very sensitive, use special infrared receiving tube to detect flame thermal radiation, and then the flame brightness changes into high and low level signal, again through the comparator compared with reference voltage threshold, reaches the threshold voltage, output low level modules.
