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.
The sensor is
compatible with various microcontroller control boards, such as the
Arduino series of microcontrollers. When using it, we provide a method
for using this sensor with the Arduino series of microcontrollers.
sensor comes with a 2.54mm anti-reverse plug white terminal. When in
use, we can connect to the MCU with DuPont cable. To facilitate wiring,
we specially designed an expansion board that is fully compatible with
this sensor and the Arduino UNO R3 microcontroller. We only need to
stack the expansion board to the UNO R3 MCU, and use a 4P double-head
XH2.54 plug wire (anti-reverse) to connect to the expansion board, which
is simple and convenient.
At the same time, the sensor comes with 2 3mm diameter positioning holes, which allows you to fix the sensor to other devices.
