10 Stück Flammensensor Modul XH2.54 Stecker 4 Pin Dupont Kabel Stecker für Arduino
Description: This is a commonly used flame sensor. It can detect flame or light source with wavelength in the range of 760 nm to 1100 nm. Its detection angle is about 60 degrees. It is particularly sensitive to flame spectrum and its sensitivity is adjustable and its performance is stable. When in use, the A0 end reads the analog value of corresponded the flame size; the D0 end is connected to an LM393 chip (comparator), we can adjust the critical point of flame size alarm by the potentiometer, and the digital value is output at D0. When the measured flame size exceeds the critical point, the D0 terminal outputs a low level; when the measured flame size does not exceed the critical point, the D0 terminal outputs a high level.
