• It can detect flame or wavelength at 760 nm at 1100 nm light source.
• the detection angle of 60 degrees has a particularly sensitive spectrum.
• Sensitivity is adjustable. (Blue is shown on the digital potentiometer adjustment.)
• The comparator output signal is better than clean waveform 15mA.
• Working Voltage 3.3V - 5V
• Output as follows: DO digital switching outputs (0 and 1) and AO analog voltage output.
• There is a fixed bolt hole for easy installation.
• PCB size: 3.2cm x 1.4cm
• It uses a large LM393 comparator.

Wiring instructions:

1.VCC: VCC3.3-5V
