This module is sensitive to the flame, but also 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
Features: 100% brand new Detects a flame or a light source of a wavelength in the range of 760nm-1100nm 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 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 (4-wire) VCC: 3.3V-5V voltage GND: GND DO: board digital output interface (0 and 1) AO: board analog output interface Note:Please keep a distance with flame, high temperature maybe burn out the sensor module.
