IR Flame Fire Sensor Module J35 LM393 (760nm-1100nm)

The VCC external 5V voltage, GND with an external GND, DO small board digital output interfaces (0 and 1), AO small board analog output interface. Comparator chip LM393 ,it is stable. 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. This module is sensitive to the flame, but aslo can detect ordinary light. Usually used as a flame alarm. On board, digital output interface can be directly connected with the microcontroller IO. Please keep a distance with flame,high temperature maybe burn out the sensor module.
