Description:
Detects a flame or a light source of a wavelength in the range of 760nm-1100 nm
Detection angle about 60 degrees, it is sensitive to the flame spectrum.
Accuracy adjustable
Operating voltage 3.3V-5V
Output
a. analog voltage output
b. digital switch outputs (0 and 1)
With a mounting screw hole
PCB size: 3cm * 1.6cm
Power indicator (red) and digital switch output indicator (green)
Comparator chip LM393 ,it is stable.
Flame detection distance, lighter flame test can be triggered within 0.8m, if the intensity of flame is high , the detection distance will be increased.
Interface Description (4-wire)
VCC -- 3.3V-5V voltage
GND -- GND
DO -- board digital output interface (0 and 1)
AO -- board analog output interface
