1.It’s able to detect light or flame source and wavelength should be within 760nm to 1100nm. The flame distance of the lighter is 80 cm. The larger the flame, the farther the test distance is.
2, the detection angle is about 60 degrees in addition the sensitivity is adjustable
4, the comparator output, the signal is clean, the waveform is good, the driving ability is strong, more than 15mA
5, with adjustable precision potentiometer to adjust sensitivity
6, output form is DO digital switch output (0 and 1) and AO is analog voltage output
7, with fixed bolt holes for easy installation therefore it becomes user friendly
8, small board PCB size: 1.26inchx0.56inch/3.2cm x 1.4cm
9. Use a wide voltage LM393 comparator and it’s working voltage 3.3V-5V
